1. Name the substance oxidised and reduced in the given reaction:MnO2

1.	1. Name the substance oxidised and reduced in the given reaction:MnO2 + 4HCI Heat MnCle 2H20 Cla
Answer» Here MnO2 is reduced to MnCl2. ie., the oxidation no.of Mn is decreased from +4 to -2. HCl is oxidised to chlorine molecule. ie.,the OXIDATION-NUMBER of chlorine is increased from -2 to 0. So MnO2 is reduced to MnCl2. HCl is oxidised to chlorine.

1. Name the substance oxidised and reduced in the given reaction:MnO2 + 4HCI Heat MnCle 2H20 Cla

Answer»

Here MnO2 is reduced to MnCl2.

ie., the oxidation no.of Mn is decreased from +4 to -2.

HCl is oxidised to chlorine molecule.

ie.,the OXIDATION-NUMBER of chlorine is increased from -2 to 0.

So MnO2 is reduced to MnCl2.

HCl is oxidised to chlorine.
