A

concentrated `H_(2)SO_(4)` on heating

B

concentrated `NaOH`

C

`(NH_(4))_(2)CO_(3)`

D

Dilute `HNO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A,B
(A)`PbSO_(4)darr +H_(2)SO_(4)` (hot and concentrated) `to Pb^(2+)+2HSO_(4)^(-)`(soluble)
(B)It dissolves forming `Na_(2)[Pb (OH)_(4)]` soluble complex.
