Will a precipitate form when an aqueous solution of (NH4)4CO3 is mixed with Fe(NO3)3

Answer 1

Solubility and Precipitation:
1. Alkali Metal Cations, ammonium cations= Soluble.
2. Nitrate Anions, Acetate Anions= Soluble.
3. Halogen anions= Soluble...except: Ag+, Cu+, Hg2 +2, and Pb+2.
4. Sulfate Anions= Soluble...except: Ba +2, Ca+2, Hg2 +2, Pb+2, Sr+2.
5. Anything else is insoluble...except: Ba(OH)2, Ca(OH)2, Sr(OH)2, CaS, SrS, BaS.
