1.	The native silver forms a water soluble compound (B) with dilute aqueous solution of NaCN in the presence of a gas (A). The silver metal is obtained by the addition of a metal (C) to (B) and complex (D) is formed as a byproduct. Write the structures of (C) and (D) and identify (A) and (B) in the following sequence :Ag + NaCN + [A] + H2O [B] + OH- + Na+ [C] + [B][D] + Ag
Answer» [A] = O₂ [B] = Na[Ag(CN)₂] [C] = Zn [D] = Na2[Zn(CN)₄]
