Question

When NH3 is added to solid Hg2Cl2, some of the mercury ions are oxidized and some are reduced. A reaction where the same substance is both oxidized and reduced is called a disproportionation reaction. Write equations for each of these half-reactions.

HELP
The total equation, which should be in your procedure manual, is
Hg2Cl2 + 2NH3 ==> Hg + Hg(NH2)Cl + NH4Cl
Can you pick out the two half reactions?
