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 acetate
C. Sodium nitrate
D. Disodium hydrogen phosphate

Answer

A

Explanation

(A) `Pb^(2+)+2Cl^(-) to PbCl_(2) darr ("white"), Ba^(2+) +2Cl^(-) to BaCl_(2)` ("water soluble")
(B) `(CH_(3)CO O)_(2) Pb " and" (CH_(3)CO O)_(2)` Ba both are water soluble salts.
(C ) Nitrates are mostly soluble in water
(D) `3Pb^(2+)+2HPO_(4)^(2-) to Pb_(3)(PO_(4))_(2) darr ("white") +2H^(+) , Ba^(2+) +HPO_(4)^(2-) to BaHPO_(4) darr ("white")`
