what is water used as a standard reference for?
409095
It's used as a reference in chemistry for almost anything matter related.\n1.  It's used as the standard of 1g/ml for density.\n2.  It's used as the standard of 1cal/g for specific heat.\n3.  Its freezing point and boiling point define the Celcius temperature scale.\nThat's all I know of, but there's probably more.

Pots, pans, houses, clothes, makeup, jewelry, cats, shoes, fish hooks, straw, etc...  A lot of the same things we use now.  The basics don't change much.  They got their water from a jug, we get it from a water bottle, but the premise is the same.

Something standard has to meet code but something code is not necessarily standard. For instance when building a house you may put a standard fiberglass tub in the bathroom, this tub has to meet the code stating that it must have an overflow drain. Thus the standard tub meets code. Well if you meet code of having an overflow drain but the tub is made of solid gold you have met the code but the tub is not a standard tub.

Water is used in about all of the chemical processes in the body. Therefore it is a waste product in most of these reactions. The very act of breathing requires the use of water. No machine is so efficient as to have absolutely no loss in any of the variables involved in it's working. Some creatures are very efficient at retaining water but at a price to other bodily functions and even then they will eventually dehydrate and die without water.\nThis is really a pretty simple concept.

1. Because it was called water beofore anyone knew it's composition\n2. Because there are common names for a lot of common chemical compounds\n3. It is easier to use a common name for something as common as water.\nI am going to have some calcium carbonate(I think that's the one) on my chips and a glass of dihydroxide. That sounds silly, doesn't it?

Water is required for the following for the body:1.for tissues, and for the blood, 2.for producing digestive enzymes, and lubricating fluids 3. for excreting the waste proucts from the body through, urine, motion, sweat etc.4. To make the body cool by evaporation by sweating  In additon to the water in the food we take about 1.5 to 2 litres is nececessary  for normal  adult.( In our body the water is 2/3 of our body weight)

<Water towers release water anytime water is being used.A water tower's purpose is holding a supply of water at a height sufficient to pressurize a water supply system.

How about something dealing with providing potable water or water purification... that's a heck of a subject and there should be tons of information about it on the Internet.  Besides... with the fact that drinkable water is becoming harder to obtain and the costs are going up to provide that commodity, water science will be a real 'Biggie' in the near future.

(m)\n\nHeavy water is dideuterium oxide, or D2O or 2H2O. It is chemically the same as normal water, H2O, but the hydrogen atoms are of the heavy isotope deuterium, in which the nucleus contains a neutron in addition to the proton found in the nucleus of any hydrogen atom. Gilbert Newton Lewis isolated the first sample of pure heavy water in 1933.

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.

You'll probably want to know typical values for drinking water and sea water.\n\nNormally, water contains dissolved salts with Na, K, Ca, Mg and depending on quality Fe and Mn as main kations and carbonate (and hydrogen carbonate), chloride, sulfate and to (hopefully) lesser extent nitrate and phosphate ions. There are numerous possibilities to combine these ions into solid salts, making the exercise fairly pointless.\n\nIf your teacher insists, Na and K for all the anions except HCO3(1-) and CO3(2-) which usually are written as Mg and Ca salts.\n\nCommon trace elements/compunds include Al, Si, NO2(1-), Li.\n\nMore or less routinely monitored heavy metal traces include As, Cd, Cr, Co, Cu, Ni, Hg, Pb, Sb, Tl, Zn

Hi there,\n\nWe have to use 'distilled' water for medical preparations.\n\nHere's why-\nNormal water contains salts like sodium chloride, calcium and magnesium salts and when we use the same kind of water in medical preparations, the chemicals in the medicines are likely to react with the salts in water. Also, if there are any physical impurities in ordinary water, it is not safe for medical preparations.\n\nHope this solved your query. If not, please let me kno and I'll be glad to assist you further. Bye!!\n\nrule wid style n luv@vinny

I don't want ot come across as a kn*b or anything but what do you mean - for use in what way? There are desalination plants that turn salt water in fresh water, marine life tends to prefer salt water...\n\nFlippantly (which no doubt will get me no points) all water is immediately available for use.

it's usually filled with deionized H2O, used of course for washings (filtrate, precipitate, etc) or adding water to ur reaction system
