Question

What is the net ionic equation for 2NaCl(aq) + Hg2(NO3)2(aq) = 2NaNO3(aq) + Hg2Cl2(s)

Answer 1

Cl-(aq) + 2Hg+(aq) + NO3-(aq) = Hg2Cl2(s)

Step-by-step explanation:

Solubility Equation

Determine the state or phase of each substance (gas=g, liquid=l, solid/non-soluble=s, aqueous/soluble=aq) in its undissociated form by using the solubility rules or a solubility table.

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

Balanced chemical equation

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

Complete Ionic Equation

The complete (or total) ionic equation includes spectator ions. Write it by breaking all the soluble ionic compounds into their respective ions.

Na+(aq) + Cl-(aq) + 2Hg+(aq) + 2NO3-(aq) = Na+(aq) + NO3-(aq) + Hg2Cl2(s)

Net Ionic Equation

The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation.

Cl-(aq) + 2Hg+(aq) + NO3-(aq) = Hg2Cl2(s)

Spectator Ions

Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ionic equation.

• Na+

• NO3-

Precipitates

Precipitates are the solid products that form in the net ionic reaction. Cl-(aq) + 2Hg+(aq) + NO3-(aq) = Hg2Cl2(s) has 1 precipitate.

• Hg2Cl2(s)
