Answer
$CH_3COCOOH(aq) + H_2O(l) \lt -- \gt CH_3COCOO^-(aq) + H_3O^+(aq)$
Work Step by Step
- Pyruvic is an acid, therefore, when $CH_3COCOOH$ reacts with water, it will donate one proton to $H_2O$, and will produce $H_3O^+$ and $CH_3COCOO^-$
- Since it produces $H_3O^+$, the solution will be considered $acidic.$.
