Question

dding a small amount of strong acid to a buffer solution will cause the ph to increase slightly. true false

Answer 1

True

The pH of a buffer solution will be affected by strong acid because strong acid dissociates completely to give H+ ions so the pH of buffer will be appreciably affected. and as the H+ concentration increased pH will decrease.When a small volume of acid is added to a buffer solution, the pH of the system decreases as an effect of the increased hydronium ions in the solution. However, when a small volume of base is added to a buffer solution, the pH of the system increases as an effect of the increased hydroxide ions in the solution.When a base is added to a buffer solution, the pH does not change. The buffer solution prevents the base from neutralizing the acid.
