Write the net ionic equation for the precipitation reaction between ammonium sulfide and cadmium nitrate.
see above.
To write the net ionic equation for the precipitation reaction between ammonium sulfide (NH4)2S and cadmium nitrate Cd(NO3)2, we first need to identify the reactants and products in the balanced chemical equation.
The balanced chemical equation for the reaction between ammonium sulfide and cadmium nitrate is:
(NH4)2S + Cd(NO3)2 -> CdS + 2NH4NO3
In this equation, (NH4)2S is the ammonium sulfide, Cd(NO3)2 is the cadmium nitrate, CdS is the cadmium sulfide (precipitate), and 2NH4NO3 is ammonium nitrate (soluble).
To write the net ionic equation, we eliminate the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the reaction. In this case, the spectator ions are ammonium (NH4+) and nitrate (NO3-) ions.
The net ionic equation will only include the ions that directly participate in the reaction. Since ammonium and nitrate ions are spectator ions, they are not included in the net ionic equation.
The net ionic equation for the precipitation reaction between ammonium sulfide and cadmium nitrate, therefore, is:
Cd2+ + S2- -> CdS
This net ionic equation shows that cadmium ions (Cd2+) react with sulfide ions (S2-) to form cadmium sulfide (CdS), which is the precipitate formed in this reaction.
