The chlorate ion ClO3−.
A chlorate (compound) is a compound that contains this group, with chlorine in oxidation state +5.
Examples
- potassium chlorate, KClO3
- sodium chlorate, NaClO3
- magnesium chlorate, Mg(ClO3)2
See category for a bigger list.
Preparation
Metal chlorates can be prepared by adding Chlorine to hot metal hydroxides, for example, KClO3:
- 3Cl2 + 6KOH → 5KCl + KClO3 + 3H2O
Industrial scale synthesis for sodium chlorate starts from sodium chloride. If the electrolysis is not done with the method described at chlorine, but a mixing of the devoloping chlorine and the sodium hydroxide is allowed, the reaction mentioned above takes place. The heating to 50-70°C is done by the electrical power applied for electrolysis.
