# Problem: Mercury(I) ions (Hg22+) can be removed from solution by precipitation with Cl–. Suppose that a solution contains aqueous Hg2(NO3)2.Write complete ionic equation to show the reaction of aqueous Hg2(NO3)2 with aqueous sodium chloride to form solid Hg2Cl2 and aqueous sodium nitrate.

###### FREE Expert Solution

We are asked to write complete ionic equation to show the reaction of aqueous Hg2(NO3)2 with aqueous sodium chloride to form solid Hg2Cl2 and aqueous sodium nitrate.

Reactants:

aqueous Hg2(NO3)2 →Hg2(NO3)2(aq)

• Hg22+(aq)
• 2 NO3-(aq)

aqueous sodium chloride → NaCl(aq)

• Na+(aq)
• Cl-(aq)

Products:

solid Hg2Cl2 → Hg2Cl2(s)

aqueous sodium nitrate → NaNO3(aq)

• Na+(aq)
• NO3-(aq)

Balanced reaction:

Hg2(NO3)2(aq) + 2 NaCl(aq) → Hg2Cl2(s) + 2 NaNO3(aq)
