  • question_answer Which pair will show common ion effect [MP PMT 1990, 99; Pb. PMT 2001]

    A)                 \[BaC{{l}_{2}}+Ba\,{{(N{{O}_{3}})}_{2}}\]             

    B)                 \[NaCl+HCl\]

    C)                 \[N{{H}_{4}}OH+N{{H}_{4}}Cl\]

    D)                 \[AgCN+KCN\]

    Correct Answer: C

    Solution :

               \[N{{H}_{4}}OH\]⇌  \[N{{H}_{4}}^{+}\ \ +O{{H}^{-}}\]            \[N{{H}_{4}}Cl\]⇌\[N{{H}_{4}}^{+}\,\,\ \ +C{{l}^{-}}\]
