Sodium chlorate is an inorganic compound with the chemical formula NaClO₃. It appears as a white powder and is highly soluble in water. Known for its strong oxidizing properties, sodium chlorate is a potent oxidizer commonly used in the production of matches, fireworks, and other products. Additionally, it exhibits disinfectant properties, making it valuable in pharmaceuticals, water treatment, and organic synthesis.
Potassium chlorate is an inorganic compound with the chemical formula KClO₃. At room temperature, it appears as a white powder or granular solid and exhibits strong oxidizing properties. Highly sensitive as an explosive component, potassium chlorate can easily detonate when heated or subjected to violent impact. Due to its powerful oxidizing ability, it’s also widely used in rocket fuels and as a key ingredient in fireworks.
