Sodium chlorate is usually white or slightly yellow crystals. The smell is salty. It is easily soluble in water. Slightly soluble in ethanol. It has a strong oxidizing effect in acidic solutions. It decomposes oxygen above 300°C. Sodium chlorate is unstable. Mixed with phosphorus, sulfur, and organic matter, it is easy to burn and explode. It is easy to absorb moisture and agglomerate, and it is toxic. Industrially, it is used to produce chlorates such as chlorine dioxide, sodium chlorite, and perchlorate.
