Question

What effect does the concentration of \[\ce{H+_{( aq)}}\] ions have on the nature of a solution?

Answer 1

Acids furnish hydrogen ions (H⁺ ions) when dissolved in water. The more the concentration of H⁺ ions in a solution, the lower its pH. Thus, an increase in the concentration of H⁺ ions in a solution leads to an increase in the acidity of the solution.
