Compounds (A) and (B) respectively are :

Answer»

`Cu(NO_3)_2 and pb(NO_3)_2`
`Cu(NO_3)_2 and Hg(NO_3)_2`
`Cu(NO_3)_2 and AgNO_3`
`Hg(NO_3)_2 and AgNO_3`

Solution :`2CU^(2+)+5I^(-)toCu_2I_2darr`(white)+`I_3^(-)` (brown solution DUE to dissolution of `I_2`)
`Hg^(2+)+2I^(-)toHgI_2dar (red) , HgI_2 darr +2I^(-)to [HgI_4]^(2-)` (soluble complex)
