What is the chemical test for water?

Answer 1

• One simple test is the fact that the pH of water is 7.0 which is neither acidic nor alkaline but neutral. A pH higher than 7 is alkaline and a pH lower than 7 is acidic.
• Another test for water is after electrolysis, hydrogen and oxygen are evolved, which are easily tested for with the splint test.
• The full proof test for water is this:

If we add white crystals of (anhydrous) copper sulphate to a substance and a blue solution is obtained, the substance is water.

• Also blue anhydrous cobalt chloride turns pink when there is addition of water to it

the equation goes like ...

CoCl2(blue) +6H2O --> CoCl2.6H2O(pink)

Answer 2

There are two test available :

(Unfortunately these two tests can only test if water is present and not the purity of the water:)

1. Put anhydrous copper(II) sulfate into the solution (its originally white). It will react to form a blue solution if water is present. :)

2. Add in anhydrous cobalt(II) chloride into the solution(it is originally pink). It will react to form a pink solution if water is present:DD

Answer 3

One simple test is the fact that the pH of water is 7.0 which is neither acidic nor alkaline but neutral. A pH higher than 7 is alkaline and a pH lower than 7 is acidic.

Answer 4

One simple test is the fact that the pH of water is 7.0 which is neither acidic nor alkaline but neutral. A pH higher than 7 is alkaline and a pH lower than 7 is acidic.

Answer 5

There are a number of different chemical tests for water. You could use any tests that look for hydrogen or oxygen for example.

Answer 6

A complete chemical analysis of water needs an enormous number of chemicals; the list is too long for WA.

Answer 7

For each contaminant of water another set of chemicals is used for testing.

Answer 8

Anhydrous copper sulphate
