Question

the pH of a solution is 2 to one ml of this solution 999ml of pure water is added then ph of resulting solution​

Answer 1

Answer:

5 is the pH

Explanation:

This is because the molarity of H+ ions in the 1rst sol is 10^(-2) so the moles present in one ml is molarity * 10^(-3) = 10^(-5).

in the new sol this is the amount of H+ ions is 10^(-5) and the molarity is 10^(-5) hence the pH is 5
