Question

What happens to the pH of the solution as you add more substance to it?

Answer 1

If it's a buffer solution, the pH remains unchanged.

If it's a normal solution, and an acidic substance is added to it, the pH lowers.

If a basic substance is added to it, the pH increases.

Answer 2

if you’re adding an acid, PH decreases. If you’re adding a base/alkali, PH increases
