By precipitation with the Cl- the Mercury ions (Hg22+) can be removed from solution. Assume a solution has aqueous Hg2(NO3)2 . How can write the net ionic equation to explain the reaction of aqueous Hg2(NO3)2 with the aqueous NaCl to form solid Hg2Cl2 and the aqueous NaNO3. How can express your answer as a chemical equation?
