On the basis of the following observatio...

On the basis of the following observations made with aqueous solutions , assign primary and secondary valencies to metals in the following compounds .

Text Solution

Verified by Experts

Primary valency = ionizable
Secondary valency = non- ionizable
`PdCl_(2).4NH_(3)`, mole of AgCl precipitated =2, so it is `[Pd(NH_(3))_(4)]Cl_(2)`
`NiCl_(2). 6H_(2)O`, moles of AgCl precipated = 2, so it is `[Ni(H_(2)O)_(6)]Cl_(2)`
`PtCl_(4).2HCl`, mole of AgCl precipitated =0, so it is `H_(2)[PtCl_(6)]`
`CoCl_(3).4NH_(3)`, mole of AgCl precipitated =1, so it is `[Co(NH_(3))_(4)Cl_(2)]Cl`
`PtCl_(2).2NH_(3)`, moles of AgCl precipated =0, so it is `[Pt(NH_(3))_(2)Cl_(2)]`
