When silver is mixed with aluminum nitrate the products are silver nitrate and aluminum metal. how many molocules of silver nitrate are produced if we have 216 grams of aluminum nitrate? STOICHIOMETRY

Aluminum metal in silver nitrate ….

You might be expecting silver metal, Ag, and aluminum nitrate, Al(NO3)3, as products. But instead all you will end up with is wet aluminum. The passivating layer of Al2O3 will prevent aluminum from reducing silver ions.

Explanation: Al(s) + AgNO3(aq) → No reaction

The two things we might do to the mixture to disrupt the Al2O3 surface will cause the Ag+ ions to react. Often a source of chloride ion is used because AlCl4^- will form, exposing the aluminum surface. But that will cause AgCl(s) to precipitate. You can also make the solution basic with NaOH and form Al(OH)4^-, but that will cause Ag2O(s) to form. (You will get Ag2O instead of AgOH.)

Concentrated acids will oxidize any aluminum metal that might be exposed if you were to add concentrated HNO3. That would simply enhance the
