Ammonium chlorate is a chemical compound from the group of ammonium compounds and chlorates .

Extraction and presentation

Ammonium chlorate can be obtained by reacting potassium chlorate with ammonium sulfate .

${\displaystyle \mathrm {2\ KClO_{3}+(NH_{4})_{2}SO_{4}\longrightarrow 2\ NH_{4}ClO_{3}+K_{2}SO_{4}} }$

It can also be done by reacting a chloric acid solution with the stoichiometrically necessary amount of ammonia or ammonium carbonate

${\displaystyle \mathrm {HClO_{3}+NH_{3}\longrightarrow NH_{4}ClO_{3}} }$

${\displaystyle \mathrm {2\ HClO_{3}+(NH_{4})_{2}CO_{3}\cdot H_{2}O\longrightarrow 2\ NH_{4}ClO_{3}+CO_{2}+2\ H_{2}O} }$

or by reaction of barium chlorate with ammonium sulfate.

${\displaystyle \mathrm {Ba(ClO_{3})_{2}\cdot H_{2}O+(NH_{4})_{2}SO_{4}\longrightarrow 2\ NH_{4}ClO_{3}+BaSO_{4}+H_{2}O} }$

properties

Ammonium chlorate is an inconsistent colorless solid that is very easily soluble in water and is in the form of small needle-shaped crystals. Care must be taken when handling the compound, as the substance sometimes explodes for no apparent reason, but certainly at temperatures above 100 ° C. Spread openly in a thin layer, the substance is safe to handle. It has a trigonal crystal structure with the space group R 3 m (space group no. 160) .
