Question

In the reaction :- MnO2 + 4HCl - MnCl2+2H2O+Cl2 (a) name the compound (i) oxidized (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

Blah blah blah

Sorry but don't know
