Addition of dilute HCl(aq) to HCOOH(aq) decreases the ionization of HCOOH. This phenomenon is strict — Ionic Equilibrium Chemistry Question
Question
Addition of dilute HCl(aq) to HCOOH(aq) decreases the ionization of HCOOH. This phenomenon is strictly due to:
Answer: C
💡 Solution & Explanation
HCl is a strong acid that fully dissociates to provide a high concentration of $H^+$. The presence of this common ion ($H^+$) forces the weak acid equilibrium of HCOOH backward, suppressing its ionization.
