Text Solution

Verified by Experts

a. `CdSO_(4)+4KCNtoK_(2)[Cd(CN)_(4)]+K_(2)SO_(4),"Complex ion" : `[Cd(CN)_(4)]^(2-)`
b. `CuSo_(4)+4NH_(3)to[Cu(NH_(3))_(4)[SO_(4)`, "Complex ion": [Cu(NH_(3))_(4)]^(2+)`
c. `AgBr+2Na_(2)S_(2)O_(3)toNa_(3)[Ag(S_(2)O_(3))_(2)]+NaBr, "Complex ion" : [Ag(S_(2)O_(3))_(2)]^(3-)`
d.`AgNO_(3)+2KCNtoK[Ag(CN)_(2)]+KNO_(3),"Complex ion": [AgCN)_(2)]^(-)`
