Mixing Al(NO3)3 (aq) and NH4OH (aq) results in the formation of a white precipitate. What is the molecular equation for this reaction?
Al3+ (aq) + 3 OH- (aq) → Al(OH)3 (s)
Al(NO3)3 (aq) + 3 NH4OH (aq) → Al(OH)3 (s) + 3 NH4NO3 (aq)
NH4OH (aq) → NH4+ (aq) + OH- (aq)
Al(NO3)3 (aq) → Al3+ (aq) + 3 NO3-(aq)
