• # question_answer Out of $C{{H}_{3}}CO{{O}^{-}}$and $O{{H}^{-}}$ which is stronger base and why?

$O{{H}^{-}}$ ions can combine with ${{H}^{+}}$ ions more readily than $C{{H}_{3}}CO{{O}^{-}}$ ions can do. Hence, $O{{H}^{-}}$ is a stronger base. Alternatively, the conjugate acid of $C{{H}_{3}}CO{{O}^{-}}$ and $O{{H}^{-}}$ are $C{{H}_{3}}COOH$ and ${{H}_{2}}O$. As $C{{H}_{3}}COOH$ is stronger acid than ${{H}_{2}}O$, the conjugate base of $C{{H}_{3}}COOH,$ viz.,$C{{H}_{3}}CO{{O}^{-}}$ will be a weaker base.
