Final answer:
The ionic compound AgCN consists of Ag+ (silver cation) and CN- (cyanide anion).
Step-by-step explanation:
The compound AgCN is composed of two ions: Ag+ (silver cation) and CN- (cyanide anion). In silver cyanide, AgCN, the silver ion (Ag+) and the cyanide ion (CN-) come together to form an ionic compound. When dissolved in water, AgCN forms a complex ion [Ag(CN)2]- with an additional cyanide ion, as indicated by the equilibrium reaction: AgCN(s) + CN- (aq) → [Ag(CN)2]- (aq). However, the simple ionic composition of the solid compound remains Ag+ and CN-.
