On the basis of the following observations made with aqueous solutions, how many of them have 6 secondary valencies ?
`{:(" Formula","Moles of AgCl precipitated per mole of the compounds with excess" AgNO_(3)),((a) PdCl_(2).4NH_(3)," "2),((b) NiCl_(2).6H_(2)O," "2),((c) PtCl_(4).2HCl," "0),((d) CoCl_(3).4NH_(3)," "1),((e) PtCl_(2).2NH_(3)," "0):}`

Text Solution

Verified by Experts

(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
