What is the Action of Concentrated Sulphuric Acid On Potassium Chlorate? - Chemistry

Question

What is the action of concentrated sulphuric acid on potassium chlorate?

Solution

Sulphuric acid reacts with KClO3 to form KHSO4, HClO4 and ClO2.   

  `3KClO_3 + 2H_2SO_4  ->  2KHSO_4 + 2ClO_4 + KClO_2 +H_2O`       

Potassium  Sulphuric               Potassium          Perchloric
chlorate       acid                 hydrogen sulphate      acid

Potassium chlorate react with sulfuric acid to produce potassium bisulfate, chlorine dioxide, potassium perchlorate and water. Potassium chlorate - solid. Sulfuric acid - concentrated solution.
