Which is the most widely used of all solvents?

water\n\n[edit] 6 seconds too slow!

chlorine is one of the most used disinfectants.  Its disinfection power and its low cost allow us to use it everyday; to wash clothes, to clean surfaces.  \nWater supplies use it as the common disinfectant, to make water safe to drink

Aromatic Hydrocarbons are used widely in the world. They are used almost everywhere. The exampleas of aRomatic Hydrocarbon are Benzene(C6H6). It is one of the most basic substance found widely in nature.  They are used in manufacturind of various drugs, dyes, and also used as non polar Solvents. Some more exampleas are Toluene(C7H8), napthalene(used as napthalene balls), etc.\n\n Aromatic amines are slightly basic compounds. They are used in many places again in the industry. They usually have and Ar-NH2 or Ar-NHR' kind of a general formula. They are also used in a variety of Places

Water is H2O. Two hydrogen and one oxygen. Water is the universal solvent because it mixes well with most substances. Water is the most common and mysterious substances on earth. Water is suppose to be a gas ,but it's a liquid at room temperature. Water has a negative side (oxygen) and a positive side (hydrogen). This is another reason why water is the universal solvent it can dissolve just about any solute because the H and O are at 102o angel which means it can pick up most solutes. 97% of the earth's water is salt water will only less than 3% is drinkable. 70% of the earth's animals live in salt water. All animals need water.

Coca-Cola is indeed the most popular soft drink in the world as it is the best selling soft drink in most countries. \n\nCoke is one of the world's most recognizable and widely sold commercial brands.

there are different levels of purity of water and other solvents. the more pure the solvent is the more expensive.\nfor most introductory labs or where the results aren't critical then walmart quality distilled or deionized water is ok.\nfor other purposes you'd want to use the really good stuff.

I would think plywood is the number one use. Some other uses come from the source below: "Wood dust is used to prepare charcoal, as an absorbent for nitroglycerin, as a filler in\nplastics, and in linoleum and paperboard (NTP 2001). Another commercial use for wood\ndust is in wood composts (Weber et al. 1993). "

During the large scale manufacturing of drugs, a certain amount of drug will migrate into the solvent. By recovering the solvent and reprocessing, this drug can be sold and yields will increase. The advantage of this is higher capacity and less hazardous waste.

PMMA is a polymer (poly-methyl-methacrylate) which can be dissolved in a number of organic solvents.  n-hexane, n-heptane, cyclohexane, benzene, toluene, ethyl benzene, styrene, acetone, ethyl ether, methanol, ethanol, methyl methacrylate(MMA), trichloromethane, tetrahydrofuran and ethyl acetate can all be used.\n\nprobably the best choice is acetone, acetic acid or ethanol since they are cheap and easy to come by.  you will probably have to heat it if the PMMA is already polymerized.

Aside from the fact that it boils at -33.5°C, ammonia is a polar molecule, so it's best solvent use would be with other polar molecules, and water and alcohols would be far better solvents.  I would classify it as a poor solvent since it would be hard to use because you would have to keep it very cold, and there are better solvents you could use.\n\nUses:  Fertilizer (as mentioned previously); manufacture of nitric acid, hydrozine hydrate, hydrogen cyanide, urethane, acrylonitrile and sodium carbonate (by Solvay process); refrigerant; nitriding of steel; condensation catalyst; synthetic fibers; dyeing; neutralizing agent in petroleum industry; latex preservative; sulfite cooking liquors; fuel cells; rocket fuel; yeast nutrient; developing diazo films.

Any acid.  Vinegar is the best probably.

in giving appropriate amount of drugs you have to know a little about concentration of solution or colloid (syrup) molality, molarity, normality, percentage by mass, by volume, by mass-volume,etc; thermochemistry as well. in physics, knowledge in heat and thermodynamics, properties of matter, hydrodynamics (flow of blood), gas laws, etc are some of the basics that you are going to use.

To answer it simply chemical engineering is used almost in all engineering disciplines - whether it is process engineering, metallurgical uses or evaluation, corrosion engineering, chemical and pharmaceutical industry, food processing or food preservation, agriculture - pest control and pesticides etc.\n\nIt helps you achieve the right blend of properties to get the right kind of steel, stainless steel, brass, copper, aluminum, silver, gold and hundreds of other alloys that  are specifically made for certain applications to name a few.

This depends on why sulfuric acid is "king".  In industry, sulfuric acid is the most used chemical by weight (other than water).  The opposite, "the serf" or "fool" would be a chemical rarely used.  The choices are too numerous to list.

Need more specifics as to your problem.\n\nHowever, I assume you are trying to do a quantitation on a UV or vis absorbing substance.\n\nMake up  a set of standards of known concentration of your analyte in the solvent you will be analyzing in.  Then do some scans over the whole wavelength range. \n\nUsually pick the wavelength at the top of the largest absorbance peak, unless that is a wavelength which will have interferences from other substances present.  If so, then pick a wavelength with good absorbance that is not subject to such interference.
