Quizplus · Accepted Answer

The addition of sodium formate, HCOONa, which is the conjugate base of formic acid, will shift the equilibrium to the left in order to consume the added base. This will result in a decrease in the concentration of H+ ions, leading to an increase in pH. Therefore, the correct answer is D.
