Write the chain of transformations Ag – AgNo3 – AgBr – Na3 [Ag (S2O3) 2] – AgCn

Ag + 2HNO3 (conc) = AgNO3 + NO2 ↑ + H2O
AgNO3 + HBr = AgBr + HNO3
AgBr + Na2S2O3 = Na [Ag (S2O3)] + NaBr
Na [Ag (S2O3)] + 2 Na2S2O3 = Na3 [Ag (S2O3) 2] + + NaBr
Na3 [Ag (S2O3) 2] + KCN = Na [Ag (CN) 2] + K2S2O3
Na [Ag (CN) 2] + AgNO3 = 2AgCN + NaNO3
