Chloric acid
Chloric acid is a colorless solution. It cannot be made pure. It only can be mixed with water. It is very reactive. Chloric acid can decompose when warmed to make perchloric acid, chlorine, chlorine dioxide, and oxygen. It is a powerful oxidizing agent. It can make things like sugar burn when it is mixed with them. Sulfur can make explosive mixtures with potassium chlorate because chloric acid can be made.
