Answer

Answer:

A. $NaOH(s)\rightarrow Na^{+}(aq)+OH^{-}(aq)$

Explanation:

Step1: Recall Arrhenius base definition

An Arrhenius base produces $OH^{-}$ in aqueous solution.

Step2: Analyze each option

  • Option A: $NaOH$ dissociates to give $Na^{+}$ and $OH^{-}$, which fits Arrhenius - base definition.
  • Option B: $HCl$ is an Arrhenius acid as it produces $H_3O^{+}$ in water.
  • Option C: $CH_3COOH$ is an acid as it donates a proton to water to form $H_3O^{+}$.
  • Option D: This is an acid - base reaction between ammonia and acetic acid, not an example of an Arrhenius base dissociation.
