Copper (II) bromate is an inorganic compound, a salt of copper metal and bromic acid with the formula Cu (BrO ₃ ) ₂ , green crystals, it dissolves in water, forms a crystalline hydrate - blue-green crystals.

Content

Getting

Dissolution of basic copper (II) carbonate in bromic acid :

{\mathsf {Cu_{3}(OH)_{2}(CO_{3})_{2}+6HBrO_{3}\ {\xrightarrow {}}\ 3Cu(BrO_{3})_{2}+2CO_{2}+4H_{2}O}}

{\ displaystyle {\ mathsf {Cu_ {3} (OH) _ {2} (CO_ {3}) _ {2} + 6HBrO_ {3} \ {\ xrightarrow {}} \ 3Cu (BrO_ {3}) _ { 2} + 2CO_ {2} + 4H_ {2} O}}}

Physical Properties

Copper (II) bromate forms green crystals. Crystalline hydrate of the composition Cu (BrO ₃ ) ₂ • 6H ₂ O — blue-green crystals — is isolated from aqueous solutions.

Chemical Properties

Crystalline hydrate loses water when heated:

{\mathsf {Cu(BrO_{3})_{2}\cdot 6H_{2}O\ {\xrightarrow {200^{o}C}}\ Cu(BrO_{3})_{2}+6H_{2}O}}

{\ displaystyle {\ mathsf {Cu (BrO_ {3}) _ {2} \ cdot 6H_ {2} O \ {\ xrightarrow {200 ^ {o} C}} \ Cu (BrO_ {3}) _ {2} + 6H_ {2} O}}}
