Explanation / Answer
1.
Chromium (III) acetate reacts with Aluminium bromide
Molecular reaction: Cr(CH3COO)3(aq) + AlBr3(aq) = CrBr3(s) + Al(CH3COO)3(aq)
Total ionic reaction: Cr3+(aq) + 3CH3COO-(aq) + Al3+(aq) + 3Br-(aq) = CrBr3(s) + Al3+(aq) + 3(CH3COO)-(aq)
Net ionic reaction: Cr3+(aq) + 3Br-(aq) = CrBr3(s)
2.
Potassium chloride and lead (II) acetate
Molecular reaction: 2KCl(aq) + Pb(CH3COO)2(aq) = PbCl2(s) + 2CH3COOK(aq)
Total ionic reaction: 2K+(aq) + 2Cl-(aq) + Pb2+(aq) + 2CH3COO-(aq) = PbCl2(s) + 2K+(aq) + 2CH3COO-(aq)
Net ionic reaction: Pb2+(aq) + 2Cl-(aq) = PbCl2(s)
3.
silver (I) nitrate and Potassium Chloride
Molecular reaction: AgNO3(aq) + KCl(aq) = AgCl(s) + KNO3(aq)
Total ionic reaction: Ag+(aq) + NO3-(aq) + K+(aq) + Cl-(aq) = AgCl(s) + K+(aq) + NO3-(aq)
Net ionic reaction: Ag+(aq) + Cl-(aq) = AgCl(s)
