On the basis of the following observations made with aqueous solutions

1.	On the basis of the following observations made with aqueous solutions, assign secondary valencies to metals in the following compounds : Formula Moles of AgCl precipitated per mole of the compound with excess of AgNO_(3) {:((i),PdCl_(2).4NH_(3),2),((ii),NiCl_(2).6H_(2)O,2),((iii),PtCl_(4).2HCl,0),((iv),CoCl_(3).4NH_(3),1),((v),PtCl_(2).2NH_(3),0):}
Answer» SOLUTION :(i) Formula = `[Pd(NH_(3))_(4)]Cl_(2)`, Secondary valencies = 4 (ii) Formula = `[Ni(H_(2)O)_(6)]Cl_(2)`, Secondary valencies = 6 (iii) Formula = `H_(2)[PtCl_(6)]`, Secondary valencies = 6 (IV) Formula = `[CO(NH_(3))_(4)Cl_(2)]Cl`, Secondary valencies = 6 (V) Formula = `[Pt(NH_(3))_(2)Cl_(2)]`, Secondary valencies = 4
