Sodium cyanide solution, when poured into excess hydrochloric acid, releases hydrogen cyanide as a gas. The reaction is NaCN(aq) + HCl(aq) → HCN(g) + NaCl(aq) Identify the conjugate acid–base pairs in this reaction out of the following. HCN and Cl- HCN and CN- CN- and HCl HCl and Cl–

Expert Solution

NaCN(aq) + HCl(aq) → HCN(g) + NaCl(aq)

Based on the given chemical reaction:

proton donor is an acid.

proton acceptor is a base.

Conjugate acid-base pair = HCN and CN^- (acid = HCN , conjugate base = CN^- )

Conjugate acid-base pair = HCl and Cl^- ( acid = HCl , conjugate base = Cl^- )
