Question

examples of redox reaction any 7 and say which undergo oxidation and reduction​

Answer 1

Answer:

7 redox reaction example

H2S + Cl2 → 2HCl + S

The O.N. of S increases from -2 to 0. So it is undergoing oxidation and O.N. of Cl2 decreases from 0 to -1. So it is undergoing reduction. Therefore it is a redox reaction.

CuO + H2 → Cu +H2O

In this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed. So, the conversion of CuO to Cu is reduction reaction. H2 is getting oxidised to H2O. So, it is oxidation reaction.

Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)

Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0.

MnO4-+ I- → MnO2 + I2

Here I- is oxidised to I2 and MnO4 - is reduced to MnO2.

Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H2O

In this reaction, Pb is getting oxidised to PbSO4 and PbO2 ias reduced to PbSO4.
