(c) 2Pb3O4 ->6PbO (s) + O2(g) is the reaction characterized by the yellow colour of the product.
- PbO is the chemical formula for lead monoxide or lead oxide. The precipitate of lead oxide is yellow in colour.
- ZnSo4 is the chemical formula for compound zinc sulphate. The solid is colourless.
- Na2SO4 is the chemical symbol for sodium sulphate and KCl is the chemical symbol for potassium chloride.
- Both the precipitates are white in colour.
