Mercury dissolves in concentrated nitric acid, with the evolution of a reddish-brown gas, just as in the reaction shown in figure 5.4 on page 188 for copper. The oxidation state of the mercury after reaction is +2. Write a balanced net ionic equation for the reaction?
Answered by Ian

Hg + 4H+NO-3 ---> Hg2+(NO3-)2
+2NO2 + 2H2O

Hg + 4H+NO-3 ---> Hg2+(NO3-)2
+2NO2 + 2H2O

The above equations are not balanced (N and O for example).
The molecular equation is
Hg + 4HNO3 ==> Hg(NO3)2 + 2NO2 + 2H2O
