Question

MnO2 + 4HCl  MnCl2 + 2H2O + Cl2 (a) Name the compound (i) oxidised, (ii) reduced. (b) Define oxidation and reduction on its basis.

Answer 1

HCl is getting oxidised here..

Because the oxidation state of Cl in HCl is -1 whereas in Cl2 it is 0..

Hence HCl is oxidised by loosing an electron .

On the other hand reduction is the gain of electron..

Hence MnO2 is getting reduced here because The oxidation state of Mn has changed from +4 to +2

Answer 2

This is right ans.......
