Question

What will be the ph of a solution that is prepared by mixing 5 ml of a strong acid of ph 2.0 and 10 ml of strong base of ph 12

Answer 1

For a question of this sort, it is imperative to know the nature of the acid, whether it is mono,di or triprotic.

We can always make an approximate prediction, but a direct answer is not to certain.

5 ml of each would react to give H20.

Therefore the pH of basic solution and H20 would be between 10-12.
