Molybdenum (V) hydroxide is an inorganic compound, molybdenum oxide-hydroxide with the formula MoO (OH) ₃ , a brown powder, does not dissolve in water.

Content

Getting

Dehydration of freshly prepared Mo (OH) ₅ (dissolution of molybdenum (V) compounds in ammonia solution):

{\mathsf {Mo(OH)_{5}\ {\xrightarrow {}}\ MoO(OH)_{3}+H_{2}O}}

{\ displaystyle {\ mathsf {Mo (OH) _ {5} \ {\ xrightarrow {}} \ MoO (OH) _ {3} + H_ {2} O}}}

Dissolution in alkaline aqueous solutions of molybdenum (III) hydroxide :

{\mathsf {Mo(OH)_{3}+H_{2}O\ {\xrightarrow {}}\ MoO(OH)_{3}+H_{2}\uparrow }}

{\ displaystyle {\ mathsf {Mo (OH) _ {3} + H_ {2} O \ {\ xrightarrow {}} \ MoO (OH) _ {3} + H_ {2} \ uparrow}}}

Physical Properties

Molybdenum (V) hydroxide forms a brown powder, does not dissolve in water.

Chemical Properties

It decomposes on heating in an inert atmosphere:

{\mathsf {2MoO(OH)_{3}\ {\xrightarrow {T}}\ Mo_{2}O_{5}+3H_{2}O}}

{\ displaystyle {\ mathsf {2MoO (OH) _ {3} \ {\ xrightarrow {T}} \ Mo_ {2} O_ {5} + 3H_ {2} O}}}

Oxidized by heating in air:

{\mathsf {4MoO(OH)_{3}+O_{2}\ {\xrightarrow {T}}\ 4MoO_{3}+6H_{2}O}}

{\ displaystyle {\ mathsf {4MoO (OH) _ {3} + O_ {2} \ {\ xrightarrow {T}} \ 4MoO_ {3} + 6H_ {2} O}}}
