Question

what effect does an increase in concentration of h+ i aq solution on the pH of solution

Answer 1

The more the concentration of H+ ions, the lower is the pH value of the solution.

Therefore, the more the H+ ions, the more acidic the solution is.

Hope it helps!

Answer 2

When the concentration of hydrogen ions increase the solution become more acidic while when the hydrogen ion decreases cause an increase in the bases in the solution.
