Getting

Dissolution of mercury (II) carbonate in perchloric acid ^[1] :

{\mathsf {HgCO_{3}+2HClO_{4}\ {\xrightarrow {}}\ Hg(ClO_{4})_{2}+CO_{2}\uparrow +H_{2}O}}

{\ displaystyle {\ mathsf {HgCO_ {3} + 2HClO_ {4} \ {\ xrightarrow {}} \ Hg (ClO_ {4}) _ {2} + CO_ {2} \ uparrow + H_ {2} O}} }

Dissolution of mercury (II) oxide in perchloric acid:

{\mathsf {HgO+2HClO_{4}\ {\xrightarrow {}}\ Hg(ClO_{4})_{2}+H_{2}O}}

{\ displaystyle {\ mathsf {HgO + 2HClO_ {4} \ {\ xrightarrow {}} \ Hg (ClO_ {4}) _ {2} + H_ {2} O}}}

Physical Properties

Mercury (II) perchlorate forms crystals that dissolve very well in water with partial hydrolysis .

It forms crystalline hydrates of the composition Hg (ClO ₄ ) ₂ • n H ₂ O, where n = 1, 2, 3, and 6.

Chemical Properties

In aqueous solutions it is hydrolyzed to form mercury (II) perchlorate oxide ^[1] :

{\mathsf {3Hg(ClO_{4})_{2}+2H_{2}O\ {\xrightarrow {}}\ Hg_{3}O_{2}(ClO_{4})_{2}+4HClO_{4}}}

{\ displaystyle {\ mathsf {3Hg (ClO_ {4}) _ {2} + 2H_ {2} O \ {\ xrightarrow {}} \ Hg_ {3} O_ {2} (ClO_ {4}) _ {2} + 4HClO_ {4}}}}

Upon contact of the solution with metallic mercury forms mercury perchlorate (I) :

{\mathsf {Hg(ClO_{4})_{2}+Hg\ \rightleftarrows \ Hg_{2}(ClO_{4})_{2}}}

{\ displaystyle {\ mathsf {Hg (ClO_ {4}) _ {2} + Hg \ \ rightleftarrows \ Hg_ {2} (ClO_ {4}) _ {2}}}}

Application

It is used as a catalyst in organic synthesis ^[2] .
