In reaction
SO2 + H2S → 2H2O + 3S
the reducing agent is –
In reaction SO2 + H2S → 2H2O + 3S, the reducing agent is H2S as it donates hygrogen to SO2.
Find out the process of oxidation , reduction. And oxidising agent ,reducing agent from the following.
1. MnO2 + 4HCL ➡ MnCl2 + 2H2O + Cl2
2.H2S + SO2 ➡ S+ H2O
3.CuO + C ➡ Cu + CO
