Content

Getting

Effect of sodium thiosulfate on soluble barium salt:

{\mathsf {BaCl_{2}+Na_{2}SO_{3}S\ {\xrightarrow {}}\ BaSO_{3}S\downarrow +2NaCl}}

{\ displaystyle {\ mathsf {BaCl_ {2} + Na_ {2} SO_ {3} S \ {\ xrightarrow {}} \ BaSO_ {3} S \ downarrow + 2NaCl}}}

Physical Properties

Barium thiosulfate forms colorless crystals.

Slightly soluble in water.

Forms crystalline compound of the composition BaSO ₃ S • H ₂ O.

Chemical Properties

Crystallohydrate loses water when heated:

{\mathsf {BaSO_{3}S\cdot H_{2}O\ {\xrightarrow {100^{o}C}}\ BaSO_{3}S+H_{2}O}}

{\ displaystyle {\ mathsf {BaSO_ {3} S \ cdot H_ {2} O \ {\ xrightarrow {100 ^ {o} C}} \ BaSO_ {3} S + H_ {2} O}}}

Reacts with soluble sulphates :

{\mathsf {BaSO_{3}S+Na_{2}SO_{4}\ {\xrightarrow {}}\ BaSO_{4}\downarrow +Na_{2}SO_{3}S}}

{\ displaystyle {\ mathsf {BaSO_ {3} S + Na_ {2} SO_ {4} \ {\ xrightarrow {}} \ BaSO_ {4} \ downarrow + Na_ {2} SO_ {3} S}}}
