Answer to Question #261455 in Inorganic Chemistry for Smiles

Question

Express the oxidation and reduction balanced overall reactions for the following.

1. (HOCI+HS^-) to (Cl^-+SO₄^2-)
2. (CH₃OH+O₂(aq) to (CO₂(g)+H₂O(I))
3. (MnO₄^-+) to MnO₂(s)

Answer 1

I) The balanced reaction

HS- + 4HOCl = SO42- + 4Cl- + 5H+

ii) The balanced reaction

2CH3OH + 3O2 = 2CO2 + 4H2O

iii)The balanced reaction

3Mn2+ + 2MnO4- + 2H2O = 5MnO2 + 4H+
