Though Ionci compounds tend to be very stable, they dissolve very easily in water. The + ions are surround by OH- ions, and the - ions by H+ ions. Every thing is able to move around freely, so there are many electrons moving around. So when a potentiol difference (voltage) is applied, there is an electric current.

When a strong electroltye is seperated (dissociated) in water, it seperated into both negative and positive charges, these charges are attracted to the electrical conductors to give it energy to light a light bulb. Try it with salt and water, like NaCl.

The KCl, definitely.  Conductivity in water is greatly enhanced by the presence of ions.  Deionized water actually has fewer ions in it than ordivnary tap water, so it's a really terrible conductor.  KCl, on the other hand, dissolves into K+ and Cl- in water, so there are a whole lot of ions in a solution of KCl.

An electrolyte is a liquid substance which acts as a medium to conduct electricity. One speaks of an electrolyte in a number of different contexts, the most common including health and fitness, and various electronics and automotive disciplines. An electrolyte is full of ions, which are atoms that have some sort of net electric charge, either positive or negative. A dilute electrolyte has a relatively small amount of ions for its volume, while a concentrated electrolyte has a high amount of ions.\n\nIn basic fuel cells, such as those used in automotive technology, an electrolyte acts as the liquid that allows ions to travel between the cathode and anode to keep the power-generating process underway, while keeping the reactive oxygen and hydrogen apart. In the type of fuel cell known as a proton exchange membrane cell, the electrolyte specifically moves protons (positively-charged hydrogen ions) to the cathode from the anode where they are produced, with the end result being the production of water and electricity.\n\nBatteries also employ an electrolyte of some sort, both to conduct electricity between the battery plates, and to store energy on the plates themselves. The electrolyte used in a battery depends on the battery's type and purpose. Most car batteries, for example, use an electrolyte which contains sulfuric acid, which is why they require careful handling. Alkaline batteries use an alkaline solution for their electrolyte. Lithium batteries use a special organic electrolyte which freezes at much lower temperatures than more traditional water-based electrolytes.\n\nIn human health, electrolytes aid in a number of vital bodily processes. Many heart and nerve functions, muscle control and coordination, and the body's ability to absorb fluids all depend on a healthy balance of electrolytes. The most common electrolytes found in the human body are sodium, potassium, magnesium, chloride and calcium. Various hormones in the body help regulate intake of these electrolytes, and the kidneys filter electrolytes which reach excessive levels. Unhealthy levels of consumption of any or all of the body's necessary electrolytes can cause serious health issues. The most common imbalances are hyper- and hypo-natremia, or excessive and insufficient levels of sodium, and hyper- and hypo-kalemia, or excessive and insufficient levels of potassium.\n\nMany sports drinks contain added potassium and sodium to help restore the body's proper electrolyte balance after intense physical exertion. After exercising heavily, it can be dangerous to ingest large quantities of water, as it may dilute existing electrolyte levels and cause physical problems. Additionally, a number of electrolyte enhanced drinks exist specifically for children and may be helpful for regular use, particularly to restore electrolyte balance after sickness which has included vomiting or dihorrea

It's a bond where electrons are shared between elements.  As opposed to ionic bonds where the charges make the bond.

On the most basic level, an electrolyte behaves as an electrically conductive medium. Because they generally consist of ions in solution, electrolytes are also known as ionic solutions.

I assume that you mean that the resistance of the solution kkeps rising with time. If you are using a Dc based system, then depending on the conductivity (1 over the resistance) electrolysis products may be building up at the electrodes and increasing the resistance. A yourself a good conductivity meter and this should eliminate the problem.\n\nThe resistance of a solution will dpend on the area of your electrodes, the distance bewteen them ,the concentration of dissolved salts in the water and the solution temperature. You will have a few things you will need to keep standard.

so that it gets ionised during electrolysis and the ions help in the conduction of electricity....

in electrochemical cells we have chemical reaction . since conversion of this chemical energy to electric energy is mainly becoz of combination of ions ..we hav electric on account of this chemical energy till we have free ions to combine once all ions of solution combines  no more energy conversion is there

If by 'undissolved' you mean why are some salts insoluble in water, then I think we are in business.\n\nIn order for a salt to be soluble it has to be energetically favorable for the ions to separate. This requires a negative gibbs free energy. G = H - TS So you have to find the H and S values for the solid to aqueous solution and see if G will be negative for a given temperature.\n\nA method I recently learned to make insolube salts more soluble is to add other ions to the water...but you have to be careful to not add a common ion...or Le Chantliear will come into play.

i think it's because in solid states, the electrostatic forces keep the positive and negative ions together.  but when placed in water, the ions separate, free to move about in the water.

In many ways, water is a miracle liquid. It is essential for all living things (on this planet at least), and it is often referred to as a universal solvent because many substances dissolve in it. These unique properties of water result from the ways in which individual H2O molecules interact with each other.\n\n The partial charge that develops across the water molecule helps make it an excellent solvent. Water dissolves many substances by surrounding charged particles and "pulling" them into solution. For example, common table salt, sodium chloride, is an ionic substance that contains alternating sodium and chlorine ions.\n\nWhen table salt is added to water, the partial charges on the water molecule are attracted to the Na+ and Cl- ions.  The water molecules work their way into the crystal structure and between the individual ions, surrounding them and slowly dissolving the salt.  The water molecules will actually line up differently depending on which ions are being pulled into solution.  The negative oxygen ends of water molecules will surround the positive sodium ions; the positive hydrogen ends will surround the negative chlorine ions.  \n\nIn a similar fashion, any substance that carries a net electrical charge, including both ionic compounds and polar covalent molecules (those that have a dipole), can dissolve in water. This idea also explains why some substances do not dissolve in water. Oil, for example, is a nonpolar molecule. Because there is no net electrical charge across an oil molecule, it is not attracted to water molecules and therefore does not dissolve in water.

In Ionic bond, elements looses or gains electron(s) and become ions and the electrostatic potential of these ions bind them\n\nIn covalent, the participating elements are bound by sharing electrons between them.

It is a polymer made up of two different monomeres. If it is used in batteries it will likely allow ion conduction, i.e. the migration of ions through the polymer. No idea whether an additional solvent is required, though.

Causes of resistance\n[edit]\n\nIn metals\n\nA metal consists of a lattice of atoms, each with a shell of electrons. This can also be known as positive ionic lattice. The outer electrons are free to dissociate from their parent atoms and travel through the lattice, creating a 'sea' of electrons, making the metal a conductor. When an electrical potential difference (a voltage) is applied across the metal, the electrons drift from one end of the conductor to the other under the influence of the electric field.\n\nIn a metal the thermal motion of ions is the primary source of scattering of electrons (due to destructive interference of free electron wave on non-correlating potentials of ions) - thus the prime cause of metal resistance. Imperfections of lattice also contribute into resistance, although their contribution in pure metals is negligible.\n\nThe larger the cross-sectional area of the conductor, the more electrons are available to carry the current, so the lower the resistance. The longer the conductor, the more scattering events occur in each electron's path through the material, so the higher the resistance. [1]\n[edit]\n\nIn semiconductors and insulators\n\nSemiconductors have properties that are part-way between those of metals and of insulators. A silicon boule has a grayish metallic sheen, like a metal, but is brittle, like glass. It is possible to manipulate the resistive properties of semiconductor materials by doping those materials with atomic elements, such as arsenic or boron, which create electrons or holes which can move across the material lattice.\n[edit]\n\nIn ionic liquids/electrolytes\n\nIn electrolytes, electrical conduction happens not by band electrons or holes, but by full atomic species (ions) traveling, each carrying an electrical charge. The resistivity of ionic liquids varies tremendously by the salt concentration - while distilled water is almost an insulator, salt water is a very efficient electrical conductor. In biological membranes, currents are carried by ionic salts. Small holes in the membranes, called ion channels, are selective to specific ions and determine the membrane resistance.\n[edit]\n\nResistance of various materials\nMaterial Resistivity, ρ\nohm-meter\nMetals 10 - 8\nSemiconductors variable\nElectrolytes variable\nInsulators 1016\n[edit]\n\nBand theory\nElectron energy levels in an insulator.\nElectron energy levels in an insulator.\n\nQuantum mechanics states that the energy of an electron in an atom cannot be any arbitrary value. Rather, there are fixed energy levels which the electrons can occupy, and values in between these levels are impossible. The energy levels are grouped into two bands: the valence band and the conduction band (the latter is generally above the former). Electrons in the conduction band may move freely throughout the substance in the presence of an electrical field.\n\nIn insulators and semiconductors, the atoms in the substance influence each other such that between the valence band and the conduction band, there exists a forbidden band of energy levels that the electrons simply cannot occupy. In order for a current to flow, a relatively large amount of energy must be furnished to an electron for it to leap across this forbidden gap and into the conduction band. Thus, large voltages yield relatively small currents.

in order to conduct electricity, the water (or any liquid really) must have some charge carriers in it.  These charge carriers are atoms that have ionized, that is, have become charged either positvely or negatively.  plain water, like from the tap, has very few charge carriers in it, but it does have some and will conduct electricity.  Adding salt to tap water increases the amount of charge carriers because the salt ionizes.  so salted tap water is a better conductor of electricity that plain tap water.  sea water already has plenty of salt in it, so it is a good conductor also.\n\n(a little known fact is that if you have completely pure water, it will not conduct electricity very easily, if at all.   I'm not sure how available pure water is.)
