Additional information

Sodium chlorate is highly soluble in water (95.7 g/100 ml at 20°C). Sodium chlorate in aqueous solutions is known for its chemical stability under environmental conditions (Urbanski 1998).

Based on the chemical structure it is expected that sodium chlorate is resistant to hydrolysis.Due to its chemical structure, sodium chlorate is considered as stable in sterile water whatever the pH is. There are no relevant metabolites, degradation or reaction products that necessitate studies to answer this point.

Sodium chlorate is rapidly biodegradable. Studies on the hydrolysis as a function of the pH are therefore not required.
