The equation Fe + 4Hg(NO3)2 -> 2Fe(NO3)3 + 4Hg

  1. Detailed information about the equation Fe + 4Hg(NO3)2 -> 2Fe(NO3)3 + 4Hg

Fe is the chemical symbol for Iron. Hg(NO3)2 is the nitrate salt of Mercury(II). When iron reacts with the nitrate salt of mercury, the products formed are Fe(NO3)3 (Iron(III) nitrate) and mercury.

  1. Reaction conditions

This reaction usually occurs when iron and mercury nitrate are in a mild acidic environment, at room temperature.

  1. Reaction process

Iron reacts with mercury nitrate to form iron nitrate and mercury. This reaction is a redox reaction. Iron is oxidized from an oxidation state of +2 to +3, while mercury is reduced from an oxidation state of +2 to 0.

  1. Phenomena occurring

When the reaction occurs, we can see the phenomenon of iron gradually dissolving in the solution and producing solid mercury along with a brown-yellow solution.
