Redox reactions ..... Oxidation -- increase in oxidation state Reduction -- decrease in oxidation state Oxidizing agent -- reactant which contains the element reduced Reducing agent -- reactant which contains the element oxidized ...0..........0 .............+2 -2 2Pb(s) + O2(g) --> 2PbO(s) Pb is oxidized, O2 is reduced, Pb is reducing agent, O2 is oxidizing agent ...0..........0 ............+4 -1 Pb(s) + 2Br2(l) --> PbBr4(s) Pb is oxidized, Br2 is reduced, Pb is reducing agent, Br2 is oxidizing agent ...0..........+1-1 ............+3 -1..............0 2Al(s) + 6HCl(aq) --> 2AlCl3(aq) + 3H2(g) Al is oxidized, H is reduced, Al(s) is the reducing agent, Cl- (or HCl) is the oxidizing agent -8/3+1 .........0..............+4-2 ...........+1-2 C3H8(g) + 5O2(g) --> 3CO2(g) + 4H2O(g) C is oxidized, O is reduced, C3H8 is the reducing agent, O2 is the oxidizing agent

Old Science Guy: ... a) OA: oxygen RA: lead No.e-

... a) OA: oxygen RA: lead No.e-: 2(2) or 4 b) OA: bromine RA: lead No.e-: 2 c) OA: H in HCl RA: Al No.e-: 2(3) or 6 d) OA: oxygen RA: carbon in C3H8 No.e-: 20 When you get a good response, please consider giving a best answer. This is the only reward we get.
