Question

Which of the following methods is generally used for preparing the $PbC{O}_3$ salts?

1: Neutralisation - insoluble base & dilute acid

2: Neutralisation - alkali & dilute acid

3: Simple displacement - active metal & dilute acid

4: Direct combination

5: Precipitation [double decomposition]

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is A 1

Salt of lead carbonate is prepared by precipitation of salt. It is done by shaking a suspension of lead salt which is less soluble than the carbonate with ammonium carbonate.

Hence, the correct option is $\left(A\right)$.
