I think the water is the end result of a chemical reaction. Water is not combustible, and never will be. It is a life giving force, unlike fire. I found out that bleach and this other cleaning liquid turn into nerve gas when mixed together. I don't have a good explaination for why this happens. It just does.

The problem with using distilled water is the local carbon dioxide in the air.  This CO2 will instanly mix with the water, and moreso over time, creating carbonic acid in the water, lowering its resistance.\n\nYou really need DEIONIZED water and keep it in a closed system made of plastic which will prevent gas transfer or ions from collecting in the water.  Then you dispense the water from a valve or something right at the point of use, to avoid CO2 contamination.  DI filters are commonly used in laser water cooling systems.  They aren't cheap, but you can buy the housing and filter elements.  You should be looking for 1Mohm or greater for your water supply.

case 1: the walls are made of conducting material\nIn this case you can safely bath, because the silica in the concrete is a better conductor of electricity than water and will conduct the electricity to the earth. How ever highly ionised water might still conduct a fraction of the electricity.\nCase 2: the walls are made of insulating material and the water storage is exposed to lightning: \nThis might be really dangerous as the lightning can be discharged only through the water and will toast you.\nCase 3: The walls are made of insulating material and the water storage is properly insulated from lightning attacks:\nDON WORRY.

Water is not a good conductor of electric current it conducts electric current because of the impurities present in it.\n\nWhy?\n\nWith this simple experiment you can verify that the distilled water presents a very low conductivity because the potential of the first circuit is much less than the developed by the battery. The small potential of this circuit is due to the presence of the H+ and OH- ions produced when some molecules of water are dissociated. However, the number of molecules of water that are dissociated is practically negligible, making the distilled water a weak electrons conductor. It is worth noting, that as the distance among electrodes increases, the resistance to the electrons transfer in the distilled water increases considerably. This fact evidences even more the low conductivity of the distilled water.\n\nWhen salt is added (NaCl) to the system, the conductivity of the system increases considerably. The water not only dissolves the salt, as well as it dissociates the salt molecule. The elementary sodium (Na) presents an excess electron and the chloride (Cl) has a strong affinity for electrons. Consequently, after dissociation, the sodium loses an electron to the chloride, forming Cl- and Na+ ions. The presence of these ions increases the conductivity of the water considerably. The positive ions (Na+) migrate to the negative electrode (linked to the pole - of the battery) and the negatives (Cl-) migrate to the positive electrodes (linked to the pole + of the pile). The conductivity of the aqueous solution water/salt is proportional to the ions concentration in the solution.\nWhen you try to measure the conductivity of tap water you can verify that it has higher conductivity in comparison with distilled water because this contains ions (less pure). The tap water has higher conductivity due to the presence of the ions: Ca2+ and Mg2+. And don´t forget, try the science at home!

water's chemical description is H2O, one atom of oxygen bound to two atoms of hydrogen. \n\n1). Pure water has a neutral pH of 7, which is neither acidic nor basic.\n\n2). Water is called the "universal solvent" because it dissolves more substances than any other liquid.\n\n3). Water is unique in that it is the only natural substance that is found in all three states -- liquid, solid (ice), and gas (steam) -- at the temperatures normally found on Earth.\n\nTypes of water\nI). Hard & soft water\nSoft water - Any water that does not contain a significant amount of dissolved minerals such as salts of calcium or magnesium.\nHard Water - water containing a high level of calcium, magnesium, and other minerals. Hard water reduces the cleansing power of soap and produces scale in hot water lines and appliances.\n\nII). Ground water & Surface water\nGround water - In hydrologic terms, water within the earth that supplies wells and springs; water in the zone of saturation where all openings in rocks and soil are filled, the upper surface of which forms the water table. Also termed Phreatic water.\n\nSurface water - Precipitation which does not soak into the ground or return to the atmosphere by evaporation or transpiration, and is stored in streams, lakes, wetlands, and reservoirs is surface water.

mercury vapor in the tube is subject to electricity which causes it to ionize.  ionization is the electrons jumping away from the atom and the returning. elecricity provides this "jump" and the energy is then released upon returning to the atom.  this release is in the form of ultraviolet rays which when they hit a "fluorescent" coating on the inside of the tube causes it to glow ( voila ! tube light )

Deionized water is NOT particularly corrosive.\n\nHowever, de-ionizing water removes those ions that normally act as buffers.  That means that any contaminant or leachate that gets in the water will cause a much larger change in the pH than would occur in typical buffered groundwater.\n\nSo, water that is deionized can easily become low or high pH (acid or caustic) corrosive.

Water will weakly (very weakly) conduct an electric current because it self-ionizes or ionizes (breaks apart) into Hydronium (H3O+) and hydroxide ions (OH-).  This isn't enough to show any conductivity with the traditional "light bulb conductivity tester."\n\nBy "water" I mean completely pure water.  Once you start dealing with water in oceans, ponds, bathtubs, etc. you've added solutes to the water.  If those solutes are able to break apart into ions (ionic and limited covalent compounds) then the water will conduct an electric current.\n\nThe question about table salt has already been answered, but if you're asking how that's different from "salt" as a chemist would use the term....  A salt is a compound made from the anion of an acid and the cation of a base... this covers most if not all ionic compounds...

Ionization occurs when air is exposed to high VOLTAGE, not high current. If you're going for cheap and easy, just put an ionizing air cleaner next to your aquarium's air pump.

It is due to the hydrogens bonding to the oxygens. Water always easily breaks up into H+ and OH-, and therefore attracts polar molecules. Also, keep in mind things dissolved into water are either polar or nonpolar, so it based on what is being dissovled into water, it can either become ionized  (break into particles that are charged) or not.

see the diagrams in the source\n\nBig Idea\nWater is comprised of two elements - hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it comes an electrolyte solution, able to conduct electricity.\n\nKey Concepts\n\n    * Ionic compounds such as salt water, conduct electricity when they dissolve in water.\n    * Ionic compounds consist of two or more ions that are held together by electrical attraction. One of the ions has a positive charge (called a cation) and the other has a negative charge (anion).\n    * Molecular compounds, such as water, are made of individual molecules that are bound together by shared electrons (i.e. covalent bonds).\n\nEssential Questions\n\n    * What happens to salt when it is dissolved in water?\n    * What are electrolytes?\n    * How can we determine the volume of dissolved ions in a water sample?\n    * How are atoms held together in an element?\n\nKnowledge and Skills\n\n    * Conduct an experiment to see that water can be split into its constituent ions through the process of electrolysis.\n    * Prepare and experiment with a 10% salt solution to better understand the process of ion exchange.\n    * Discuss and research the "softness" and "hardness" of water.\n    * Use the periodic table to identify elements and learn their characteristics.\n\nPrior Knowledge\n\n    * Define the difference between ionic and molecular compounds.\n    * Salt consists of sodium (Na) and chloride (Cl).\n    * Water is a tiny, V-shaped molecult with the molecular formula H2O.\n    * A basic understanding of how a battery works.\n    * Atoms are made of a positive nucleus surrounded by negative electrons.\n    * An atom's electron configuration, particularly the outermost electrons, determines how the atom can interact with other atoms.\n    * All matter is made up of atoms.\n    * Atoms of any element are alike, but different from atoms of other elements.\n\nCommon Preconceptions\n\n    * Students may think - "Water is a good conductor of electricity." Water is a very poor "conductor" of electricity. (The ionization constant for water is very small.) The reason it is dangerous to insert a light bulb while standing in a puddle of water is that water is a great solvent for ionic compounds. Tap water and fresh water typically contain dissolved ions in sufficient concentrations to enable the solution to be conductive. However, ions in solution carry the charge and are therefore responsible for the current, not the water itself.\n    * Students may think - "Electrons can flow through solutions." In "conduction of electricity" through solutions, electrons themselves do not pass through the solutions. Rather, the charge balance is maintained in the solution by movement of cations and anions toward the electrodes where charge transfer takes place at the solution interface.\n      Water is comprised of two elements - hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it comes an electrolyte solution, able to conduct electricity.\n\nConcept Map\nThis lesson and activity relates to the branch "Phases of Water" from the comprehensive Aquarius Concept Map - Water & its patterns on Earth's surface.\n\nBackground\nIn chemistry, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. An ionic compound, in this case salt, is dissolved with an appropriate solvent, such as water, so that its ions are available in the liquid. An electrical current is applied between a pair of inert electrodes immersed in the liquid. The negatively charged electrode is called the cathode, and th positively charged one the anode. Each electrode attracts ions which are of

Pure water is *not* a good conductor of electricity.  Dissolved ions are necessary to conduct electricity and at room temperature, there is only 10^-7 mol/L of H+ and OH- in pure water.\n\nDissolving salts (including strong acids) in water greatly increases the conductivity of the solution.\n\nTap water is a modest conductor of electricity because of dissolved ionic minerals and impurities.\n\nHeating water increases its dissociation constant making more H+ and OH- available in solution.

sodium/ potassium pump is what enables any living cell that thrives in water media (that includes all human cells) to keep an isotonic concentration of the positivelly charged sodium ion vs. its counteractive potassium equivally monocharged cation. This is insured by an active transmission of the potassium cation into the cell, with the concurring release of the sodium cation out of the cell, against all principle of osmotic pressure. This requires important usage of energy, as supplied by the continuous Krebs cycle, generating the higher energy levelled ATP. This pump is always active and its dysfunctionment will result into the misconcentration of the solutes in the cell, that will be fatal

Pure water, H2O is a terrible conductor of electricity, however, water that has hard water deposits and other impurities in it is a great conductor
