Predict the precipitate that forms when aqueous solutions of silver sulfate and Aluminum Chloride react to form products in a double replacement reaction.Identify the:- Skeleton Equation- Balanced reaction equation with states - Complete Ionic Equation- Net Ionic Equation- Spectator Ions
The skeleton equation would be: Ag2SO4 + NH4Cl - AgCl + (NH4)2SO4 But this is not a balanced equationThe balanced equation with states noted would read: Ag2SO4(aq) + 2NH4Cl(aq) - 2 AgCl(s) + (NH4)2SO4(aq) Here the silver and chloride react to yield silver chloride and form a precipitate solidHowever since many of the species are in the aqueous form the correct notation is in the ioinc format which reads (Complete ionic equation): 2 Ag (+)(aq) + SO4 (-2)(aq) + 2 NH4 (+)(aq) + 2Cl (-)(aq) - 2 AgCl(s) + 2 NH4 (+)(aq) + SO4(-2)(aq) As can be seen there are ions that do not react, and stay in solution, and these are called spectator ionsIn this case the spectator ions are NH4 (+) and SO4 (-2)This leaves the net ionic reaction to be: 2 Ag (+)(aq) + 2 Cl(-)(aq) - 2 AgCl (s) Since there is a factor of 2 throughout the equation it may be simplified to give: Ag (+)(aq) + Cl(-)(aq) - AgCl(s) Hope this helps
