Solution A increases its acidity. This means that the

Question

Quizplus · Accepted Answer

An increase in acidity means an increase in the concentration of hydrogen ions (H+), so the number of hydrogen ions has increased. This directly corresponds to a decrease in pH, but the question specifically asks for the reason for the increase in acidity. The solution will also accept fewer protons, as it already has more hydrogen ions present. The solution is not necessarily closer to neutrality, as that would mean a pH of 7, which may or may not be the case depending on the initial pH of the solution.
