Question

49. When the following oxidation-reduction equation representing a reaction that takes place in acidic solution is correctly balanced using the smallest possible whole number coefficients. the coefficients before HSO3^-, MnO4 and the H2O are: HSO3^- + MnO4^- = Mn^2+ + SO4^2- 50. In the oxidation-reduction reaction below: ClO3 + Cl = Cl2 + ClO2 a) O is oxidized and Cl is reduced. b) Cl is oxidized and O is reduced. c) Cl is both oxidized and reduced. d) O is both oxidized and reduced. e) None of the above is true.

Answer 1

49. H⁺ + 5HSO₃^- + 2MnO₄^- = 2Mn²⁺ + 5SO₄^2- + 3H₂O

50. c) Cl is both oxidized and reduced
