pH of puredistilled de-ionised water at 25oC is pH = 7.
However, tap water, because of additives put inot it by the water-companies, decreases the pH to about pH = 6.7
NB One of the additives is Chlorine gas. In water, chlorine simultaneously form HCl & HClO, both of which are acids.
Chlorine is added as a bacteriocide to water.

Does water have a measurable pH value?
yes, pH can be measured in a water (an aqueous) solution.
Does boiling water affect its pH?
Adding water will affect the pH. Adding water will shift the pH towards the neutral mark. In the case of an alkaline solution, there will be a decrease in pH.
PH of salts insoluble in water?
Salts that are insoluble in water typically do not affect the pH of the solution. This is because they do not dissociate into ions in water to contribute to the H+ or OH- ions that determine pH. If there are impurities or other substances present that can dissolve and affect pH, then the pH may change.
