Question

How does a ph of a solution change if the base is diluted?

Answer 1

The pH value of a acidic solutionincreases with dilution and the pHvalues of a basic solution decreases with dilution.
It is because by dilutionthe concentration of the H+ ions of an acid reduces and by dilution the concentration of the OH- ions of abase reduces.

Answer 2

Explanation:

the pH of a basic solution is greater than 7. but when the solution is diluted the basic pH reduces to be like as in pure water that is closer to 7. when the solution is diluted of pH value decreased for basic solution and increased for acidic solution that is nearly 7
