Strategy: Identify the major product of anodic oxidation of sulphuric acid or its salts.
Step 1: Electrochemical Reaction Electrolysis of cold, concentrated sulphuric acid or acidified sulphate solutions at high current density results in the dimerization of sulphate ions: The product is Peroxodisulphuric acid (Marshall's acid).
Step 2: Formula The chemical formula for peroxodisulphuric acid is , which can be written showing the peroxide linkage as or .
