Which of the following gives a precipitate with `Pb(NO_(3))_(2)` but not with `Ba(NO_(3))_(2)` ?

Options

A. Sodium chloride
B. Sodium sulphate
C. Disodium hydrogen phosphate
D. Sodium chromate

Answer

B,C

Explanation

(A)`Pb(NO_(3))_(2)+2NaCl to PbCl_(2) darr("white")+2NaNO_(3)`
`Ba(NO_(3))_(2)+2NaCl to BaCl_(2) +2NaNO_(3) , BaCl_(2)` is soluble in water
(B)`Na_(2)SO_(4)` gives white precipitate of `PbSO_(4)` and `BaSO_(4)` with `Pb(NO_(3))_(2)` and `Ba(NO_(3))_(2)` respectively.
( C)Disodium hydrogen phosphate gives white precipitate with both salts.
`HPO_(4)^(2-) +Ba^(2+) toBaHPO_(4) darr("white"),HPO_(4)^(2)+Pb^(2+)toPbHPO_(4)` (white)
(D)`Pb^(2+) + CrO_(4)^(2-) to PbCrO_(4) darr ("yellow"),Ba^(2+)+CrO_(4)^(2-) to BaCrO_(4) darr` (yellow)
