Question

How does salt affect the pH of water?

Answer 1

Common salt would not affect the `pH` of water to any extent.....

Explanation:

`NaCl(s) stackrel(H_2O)rarrNa^(+) + Cl^(-)`

Neither sodium ion nor chloride ion effects water hydrolysis.

There are of course other salts, for instance, sodium fluoride, that would lead to hydrolysis:

`NaF(aq) +H_2O(l) rightleftharpoonsHF(aq) + HO^-`
