Balance the redox reactions given below. Show your work on a separate sheet of paper. Write the balanced oxidation and reduction half reactions; also identify the oxidizing agent and the reducing agent. All reactions are to be balanced in acidic media, except when OH- is shown.
Balance the redox reactions given below. Show your work on a separate sheet of paper. Write the balanced oxidation and reduction half reactions; also identify the oxidizing agent and the reducing agent. All reactions are to be balanced in acidic media, except when OH- is shown.Explanation / Answer
1) FeS + NO3- + H+ ----------------> NO2 + Fe3+ + SO42- + H2O
Oxidation half:- FeS ------------> Fe3+ + SO42- + 9e-....................(1)
Reduction Half :- NO3- + e- ----------> NO2 .................(2)
overall balanced reaction = (!) + 9*(2)
FeS + 9NO3- + 10H+ ---------------> 9NO2 + Fe3+ + SO42- + 5H2O
2) Cl2 + OH- -----------------> Cl- + ClO3- + H2O
Oxidation half:- Cl2 ------------> 2ClO3- + 10e- ..............(1)
Reduction Half:- Cl2 + 2e- ------------> 2Cl- ....................(2)
Overall reaction = (1) + 5*(2)
6Cl2 + 12OH- ----------------> 2ClO3- + 10Cl- + 6H2O
