1 answer

In the reaction \( \text{HCl} + \text{H}_2\text{O} \rightarrow \text{Cl}^- + \text{H}_3\text{O}^+ \), HCl donates a proton (H\(^+\)) to water (H\(_2\)O), which leads to the formation of the conjugate base (Cl\(^-\)) and the hydronium ion (H\(_3\)O\(^+\)).

From this analysis, we can conclude that:

  • HCl is an acid.
  • Cl\(^-\) is the conjugate base of HCl.
  • H\(_2\)O acts as a base in this reaction, and H\(_3\)O\(^+\) is the conjugate acid formed from water.

Thus, the correct statement is:

HCl is an acid, and Cl– is its conjugate base.
