Question

Aqueous solution of acetic acid contains

• A. $CH_3COO^-$ and $H^+$
• B. $CH_3COO^-, H_3O^+$ and $CH_3COOH$
• C. $CH_3COO^-, H_3O^+$ and $H^+$
• D. $CH_3COOH ,CH_3COO^-$ and $H^+$

Answer 1

Answer: (B)

$CH_3COO^-, H_3O^+$ and $CH_3COOH$

Answer 2

The aqueous solution of acetic acid ionise as follows:
$H_2O+_{Base}^{CH_3COOH} \rightleftharpoons _{Acid}^{CH_3COO^-} +H_3O^+$
So, the aqueous solution of acetic acid contains $CH_3COO^-$, $H_3O^+$ and $CH_3COOH$.
