Tests for Group II Lead Ion

Lead is a soft grey metal. It is used in shots and weights. Lead is found in many salts like lead chloride and lead sulphate as lead (II) ion. In group II, lead (II) ions are precipitated as their sulphides by passing hydrogen sulphide gas through their solution. Lead (II) ions on reaction with conc. nitric acid and sulphuric acid to form a white precipitate of lead acetate. These ions also form yellow precipitate of lead iodide and lead chromate on reaction with potassium iodide and potassium chromate respectively.

 

This video explains how to test for the presence of group II lead ion in a given salt.
