Question

In the double displacement reaction between aqueous potassium iodide and aqueous lead nitrate, a
yellow precipitate if 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

Answer 1

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