Pb2+ + 30- P bO2 + H2S03 Water appears in the balanced equation as a (reactant, product, neither) with a coefficient of (Enter 0 for neither.) Which species is the oxidizing agent?

Answer 1

| Half Reactions are : Port Pbo soy Hesos is Balancing o by adding Hoo | Pb2+ + 2H20 > PbO2 son Ho soz + Heo (1) Balancing H by adeling H+ Pb+*+ 240 — PbQs+ 4H+ som + 4H+_ He fos + Heo qil Balancing charge by adding po - Pb2+ + 2H2O > PbO2 + 4H+ + 2 - 0 sor-+ 4H+20o y H₂SO3 + H₂O - (IV) Adding both Equations ① and ① same terms on opposite side of Pb2+ + sai? + H20 > Phoz + H2 Soz and Cancelling arrow. (Balanced) as a loo Water reactant abbears " with in a the balanced coefficient of reaction 1. In the Reaction oxidation from +2 to ty while from +6 to +4. oo and hence sou is the state of Pb increases that of s decreases soy is getting reduced Oxidizing agent.
