Malonic acid reacts with bromine to give bromomalonic acid . Process C sees the blue change to red and resets the chemical clock for the next oscillation. Hazards Because sulfuric acid is a strong acid and a powerful dehydrating agent, it can cause burns. Spills on skin should be washed with copious amounts of water and treated medically. Spills on inantimate surfaces should be neutralized with sodium bicarbonate and rinsed clean.
Malonic acid is a strong irritant to skin, eyes and mucous membranes.
Bromates are strong oxidizing agents. Mixtures of bromates with finely divided organic materials, metals, carbon or other combustible materials are easily ignited, sometimes explosively. Ingestion of potassium bromate can cause vomiting, diarrhea and renal injury. Do not directly inhale the minor amount of bromine generated. Protect the class with a splash shield.
