The present disclosure provides a method for distinguishing potassium chlorate from potassium bromate, including the following steps: using a 'HCHO—NaHSO—NaSO' pH clock system as a distinguishing solution, and distinguishing the potassium chlorate and the potassium bromate according to different responses, namely different induction times, of the pH clock system, caused by the potassium chlorate and the potassium bromate, respectively. In the present disclosure, the pH clock system provided by the distinguishing method has an intuitive graph, and can easily and quickly distinguish the potassium chlorate and the potassium bromate; meanwhile, the distinguishing method has simple equipment, a high accuracy, and easy operation and observation.
