13. 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

Solution

lead acetate because lead sulphate being insoluble will not form aqueous solution. Other salts ammonium nitrate and potassium sulphate do not possess the lead ion, therefore lead iodide cannot be formed using them.
