1. The problem statement, all variables and given/known data Predict products (and then write formula unit, total ionic unit & net ionic equations) 1. Sodium Nitrate, Ammonium sulfate and Iron (III) acetate. 2. Na3PO4 + RbClO3 + Sr(NO3)2 2. Relevant equations ----------- 3. The attempt at a solution 1. NaNO3 + (NH4)2S + Fe(CH3CO2)3 I just don't know how to decide what parts will be "spectator ions" and how the 3 products will work out.... I know it deals with acids and bases, but my prof went through it really fast and I tried reading our textbook but it didn't help very much with the 3 reactants, and he went out of town for a conference so I couldn't ask him for help.... I think that Fe and S will come together to make a precipitate which would be Fe2S3 and then I'm assuming that the NH4CH3CO2 would then combine together, leaving the NaNO3 as the spectator ions?
