1
Give an equation to show Sn2+ as a reducing agent
Sn2+ + I2 = Sn4+ + 2I-
2
Give an equation to show PbO2 as an oxidising agent
PbO2 + 4HCl = PbCl2 + 2H2O + Cl2
3
Give an equation to show CO behaving as a reducing agent
Fe2O3 + 3CO = 3CO2 + 2Fe
4
Show CO2 behaving as an acidic oxide
CO2 + 2NaOH = Na2CO3 + H2O
5
Show how PbO is an amphoteric oxide
1. PbO + 2HCl(conc) = PbCl2 + H2O
2. PbO + 2OH- + H20 = [Pb(OH)4]2-
