Explanation:

pH is a measure of hydrogen ion ($\text{H}^+$) concentration; lower pH means higher $\text{H}^+$ concentration. Acids release $\text{H}^+$ in water, increasing their concentration and lowering pH, while bases reduce $\text{H}^+$ concentration and raise pH.

Answer:

An acid and the amount of H+ increases.
