JEE Main & Advanced Chemistry Equilibrium Question Bank Electrical conductors, Arrhenius theory and ostwald's dilution law

  • question_answer The following equilibrium exists inaqueous solution, \[C{{H}_{3}}COOH\]⇄\[C{{H}_{3}}CO{{O}^{-}}+{{H}^{+}}\] if dil HCl is added, without change in temperature, the                   [UPSEAT 2000, 02]

    A)                 Concentration of \[C{{H}_{3}}CO{{O}^{-}}\] will increase

    B)                 Concentration of \[C{{H}_{3}}CO{{O}^{-}}\] will decrease

    C)                 The equilibrium constant will increase

    D)                 The equilibrium constant will decrease

    Correct Answer: B

    Solution :

                    Due to common ion effect of \[{{H}^{+}}\].
