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
If lead nitrate is not available, we can use lead acetate in place of it. We cannot use lead sulphate because it is insoluble. In ammonium nitrate and potassium sulphate, the ions are different. We can only use the compound of Pb not any other metal.
