  • question_answer the charge balance equation of species in 0.100 m acetic acid solution is given by

    A) \[[{{H}^{+}}]=[C{{H}_{3}}COO]\]

    B) \[[{{H}^{+}}]=[O{{H}^{-}}]\]

    C) \[2[{{H}^{+}}]=[OH]+[C{{H}_{3}}CO{{O}^{-}}]\] 

    D) \[[{{H}^{+}}]=[O{{H}^{-}}]+[C{{H}_{3}}CO{{O}^{-}}]\]

    Correct Answer: C

    Solution :

    \[C{{H}_{3}}COOHC{{H}_{3}}CO{{O}^{-}}+{{H}^{+}}\] \[H.OH\overline{O}H+{{H}^{+}}\] i.e., \[2{{H}^{+}}=[\bar{O}H]+[C{{H}_{3}}CO{{O}^{-}}]\] Hence, the correct option is [c].
