Getting

Alkaline precipitation of molybdenum (III) salts:

{\mathsf {MoCl_{3}+3NaOH\ {\xrightarrow {}}\ Mo(OH)_{3}\downarrow +3NaCl}}

{\ displaystyle {\ mathsf {MoCl_ {3} + 3NaOH \ {\ xrightarrow {}} \ Mo (OH) _ {3} \ downarrow + 3NaCl}}}

Physical Properties

Molybdenum (III) hydroxide forms a black powder, does not dissolve in water.

Chemical Properties

Decomposes on heating:

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

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

Reacts with alkaline aqueous solutions with hydrogen evolution :

{\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}}}
