Detailed Solution

The correct chemical formula of red lead is Pb₃O₄, also known as lead tetroxide. This compound is a bright red or orange solid commonly used as a pigment in paints and as a rustproof primer.

Explanation:

Chemical Composition: Red lead consists of lead in two oxidation states: Pb(II) and Pb(IV). The formula Pb₃O₄ indicates that for every three lead atoms, there are four oxygen atoms. This composition reflects a mixed valence compound, where two lead atoms are in the +2 oxidation state, and one is in the +4 oxidation state.
Physical Properties: Red lead appears as a bright red or orange crystalline solid. It is insoluble in water and has a density of 8.3 g/cm³. When heated to 500°C, it decomposes to lead(II) oxide and oxygen.
Uses: Red lead is primarily used as a pigment in paints, especially for rustproofing iron and steel. It has also been used in the manufacture of batteries and as a curing agent in some rubber compounds.
