Question

use the reaction to answer the question. hcl + h₂o → cl⁻ + h₃o⁺ which statement about the reaction is correct? (1 point) h₂o is an acid, and h₃o⁺ is its conjugate base. h₂o is an acid, and cl⁻ is its conjugate base. hcl is an acid, and cl- is its conjugate base. hcl is an acid, and h₃o⁺ is its conjugate base.

Explanation:

In an acid - base reaction, an acid donates a proton ($H^+$) and forms its conjugate base. Here, $HCl$ donates a proton to $H_2O$ to form $Cl^-$ and $H_3O^+$. According to the definition of conjugate acid - base pairs, when an acid donates a proton, the resulting species is its conjugate base. So, $HCl$ is an acid and $Cl^-$ is its conjugate base.

Answer:

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