Consider the following aqueous equilibrium for a formic acid solution, HCOOH(aq)$\leftrightarrows$ H⁺(aq)+ HCOO^-(aq).Suppose hydrogen chloride gas is dissolved in the solution.Which of the following statements regarding the resulting solution is NOT correct? Ignore any volume changes.

Question

Quizplus · Accepted Answer

Dissolving hydrogen chloride gas in the solution will increase the concentration of H+ ions, which will shift the equilibrium to the left in order to decrease the concentration of H+ ions. This means that the concentration of H⁺ will increase and the concentration of HCOOF1F1F1S1^F1F1F10 will decrease. However, the value of K_a is a constant for the equilibrium and does not change with changes in concentration or pH, so it will not increase. Therefore, the statement that is NOT correct is E.
