alleryChoose the silver-anode oxidation equation.
AAg(s) + 2CN−(aq) → [Ag(CN)2]−(aq) + e−
B[Ag(CN)2]−(aq) + e− → Ag(s) + 2CN−(aq)
CAg(s) + CN−(aq) → [Ag(CN)2]−(aq) + e−
DAg(s) + 2CN−(aq) + e− → [Ag(CN)2]−(aq)
Answer & Solution
Correct answer: A. Ag(s) + 2CN−(aq) → [Ag(CN)2]−(aq) + e−
Silver atoms are oxidised and combine with cyanide ions to replenish the complex in solution.
