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
Lead acetate can be used in place of lead nitrate because lead acetate is also water soluble like lead nitrate.
The chemical equation for this reaction is
When potassium iodide and lead acetate are mixed, a bright yellow precipitate of lead iodide is seen. Lead iodide is unusually soluble in hot water and forms crystals on cooling.
