Question

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

Explanation:

According to the Brønsted - Lowry acid - base theory, an acid donates a proton ($H^+$). In the reaction $HCl + H_2O
ightarrow Cl^-+H_3O^+$, $HCl$ donates a proton to $H_2O$. The species formed when an acid donates a proton is its conjugate base. So, when $HCl$ donates a proton, it forms $Cl^-$, which is its conjugate base.

Answer:

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