  • A$\text{HCl(aq)} \rightarrow \text{H}^+(aq) + \text{Cl}^-(aq)$; $\text{CH}_3\text{COOH(aq)} \rightleftharpoons \text{H}^+(aq) + \text{CH}_3\text{COO}^-(aq)$
  • B$\text{HCl(aq)} \rightleftharpoons \text{H}^+(aq) + \text{Cl}^-(aq)$; $\text{CH}_3\text{COOH(aq)} \rightleftharpoons \text{H}^+(aq) + \text{CH}_3\text{COO}^-(aq)$
  • C$\text{HCl(aq)} \rightarrow \text{H}^+(aq) + \text{Cl}^-(aq)$; $\text{CH}_3\text{COOH(aq)} \rightarrow \text{H}^+(aq) + \text{CH}_3\text{COO}^-(aq)$
  • D$\text{HCl(aq)} \rightleftharpoons \text{H}^+(aq) + \text{Cl}^-(aq)$; $\text{CH}_3\text{COOH(aq)} \rightarrow \text{H}^+(aq) + \text{CH}_3\text{COO}^-(aq)$
