Question

Action of heat on the following: FeSO3, ZnSO3, MnO2+HCl(conc.) Ag(NO3) CaSO3 NaCl+MnO2+conc.H2SO4 please Tell few basic observations and the reaction which takes place

Answer 1

1. FeSO3 = FeO + SO2 (in inert atmospere). If in air 4FeSO3 + O2 = 2Fe2O3 + 4SO2. Decomposition, gas release. 2. ZnSO3 = ZnO + SO2. Decomposition, gas release. 3. MnO2 + 4HCl = MnCl2 + Cl2 + 2H2O. Gas release. 4. 2AgNO3 = 2Ag + 2NO2 + O2. Decomposition, gas release. 5. CaSO3 = CaO + SO2. Decomposition, gas release. 6. 2NaCl + MnO2 + 2H2SO4 = Cl2 + MnSO4 + Na2SO4 + 2H2O. Gas release.
