Barium chlorite is a chemical compound from the group of chlorites .

Extraction and presentation

It is obtained in the laboratory by reacting chlorine dioxide with barium hydroxide and hydrogen peroxide :

${\displaystyle \mathrm {2\ ClO_{2}+Ba(OH)_{2}\cdot 8\ H_{2}O+H_{2}O_{2}\ \longrightarrow \ Ba(ClO_{2})_{2}+O_{2}+10\ H_{2}O} }$

properties

Barium chlorite is a solid which decomposes explosively when heated to 190 ° C. It also occurs as hydrate Ba (ClO ₂ ) ₂ · 3.5 H ₂ O, which has a monoclinic crystal structure with the space group C 2 / c (space group no. 15) .

use

Barium chlorite can be used to make chlorous acid or sodium chlorite .
