• # 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].
