Solution
The compound A is Cd(CH3COO)2 The compoundB is [Fe(CH3COO)]2+ The compoundC is CdS The compoundD is [Cd(NH3)4]2+ The compoundE is [Cd(CN)4]2− Cd(CH3COO)2 reacts with neutral ferric chloride solution to give blood red colour of [Fe(CH3COO)]2+ Cd(CH3COO)2+2FeCl32[Fe(CH3COO)]2++CdCl2+2Cl2 Cd(CH3COO)2 reacts with hydrogen sulphide in presence of HCl to form yellow ppt of CdS Cd(CH3COO)2+H2SHCl−−→CdS↓(yellow)+2CH3COO−+2H+ CdS is soluble in nitric acid but insoluble in yellow ammonium sulphide (YAS). Cd(CH3COO)2 reacts with aq ammonia to form white ppt which is soluble in excess of ammonia to form [Cd(NH3)4]2+ Cd(CH3COO)2+4NH3→[Cd(NH3)4]2++2CH3COO− Cd(CH3COO)2 reacts with aq KCN solution to form white ppt which is soluble in excess of aq KCN to form [Cd(CN)4]2−. Cd(CH3COO)2+4KCN→[Cd(CN)4]2−+2CH3COO−+4K+
