In the double displacement reaction between aqueous potassium iodide and aqueous lead nitrate, a yellow precipitate of lead iodide is formed. While performing the activity if lead nitrate is not available, which of the following can be used in place of lead nitrate?
A
Lead sulphate (insoluble)
B
Lead acetate
C
Ammonium nitrate
D
Potassium sulphate
Text Solution
Verified by Experts
The correct Answer is:
B
Lead acetate can be used in place of lead nitrate because like lead nitrate, it is also a soluble salt in water. The reaction is `underset("Lead acetate")(Pb(CH_(3)COO)_(2))+2KI tounderset(("Yellow ppt."))underset("Lead iodide")(PbI_(2))+2CH_(3)COO^(-)K^(+)` Lead sulphate is insoluble in water, so it cannot be used.
