Consider the following aqueous equilibrium for a formic acid solution, HCOOH(aq) ⇄ H⁺(aq) + HCOO^-(aq).Suppose solid sodium hydroxide is added to the solution.Which statement below regarding the resulting solution is FALSE? Ignore any volume changes.

Question

Quizplus · Accepted Answer

Adding sodium hydroxide to the solution of formic acid neutralizes the H+ ions, causing the equilibrium to shift right, which increases the pH and the concentration of formate ions (HCOO-), while decreasing the concentration of H+. However, the value of the acid dissociation constant (Ka) or its base dissociation constant (Kb) does not change because these are intrinsic properties of the substance that do not depend on concentration changes.
