1.

Compounds (C ) and (D) respectively are :A. `AgNO_3 and Hg(NO_3)_2`B. `AgNO_3 and Cu(NO_3)_2`C. `Pb(NO_3)_2 and Bi(NO_3)_3`D. `AgNO_3 and Bi(NO_3)_3`

Answer» Correct Answer - C
`Pb^(2+)+2I^(-)toPbI_2 darr ` (yellow), insoluble in `NH_3` solution.
`PbI_2 + 2I^(-)to [PbI_4]^(2-)`(soluble complex)
`PbI_2` is moderately soluble in boiling water giving a colourless solution.
`Bi^(2+)+3I^(-)to BiI_3 darr` (black) , `BiI_3 darr+I^(-) to [BiI_4]^(-)` (soluble complex)
