The halates are oxy-anions which contain a halogen.
They are good oxidizing agents and will oxidize, for example, iron(II) to iron(III) and iodide to iodine . Sodium chlorate(I) is found in bleach and sodium chlorate(V) is used as a weed killer. |
|
Sodium chlorate(V) (sodium chlorate) and sodium chlorate(VII) (sodium perchlorate) are available as solids. On heating the solids thermal decomposition takes place forming oxygen gas:
|
2NaClO3(s) ⇒ 2NaCl(s) + 3O2(g) |
