Tap water has been treated with chemicals to make it safe for drinking, not to mention that local minerals and debris from the pipes could make for a bad test sample. Pure water is a 7 on the scale, a true neutral.

Normally, you would choose a problem or question to investigate first, and then determine what liquids might be useful for experimental purposes; it would be doing things backwards to first select a liquid, and then try to figure out what kind of experiment you could do with it - but if that's the way you want to do it, I'm sure it is possible.

If you write this as a balanced chemical equation, water will form as a result. You must account, in other words, for all the elements.

Chemical equation for hydrogen to water vapor?
The chemical equation for hydrogen to water vapor is not possible as stated. In order for hydrogen to form water in any physical state, it must combine with oxygen. The following are the word equation and the chemical equation for hydrogen and oxygen combining to form water. Hydrogen gas plus oxygen gas produces water. 2H2 + O2 --> 2H2O
If the melting of water is physical or chemical change?
physical Water cannot melt because it is a liquid. However, a snowflake or an icicle can melt because they are solid states of water. You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
What are chemicals formulas constructed from?
Chemical formulas are constructed from elements contained in a given substance. First the composition must be determined by chemical analysis.
What kind of change must occur for an element to be removed from its compound?
a chemical change
