Question

Identify the substance oxidised and reduced in the following chemical equation MnO2+ 4Hcl = = =》MnCl2+Cl2+2H2o

Answer 1

Oxidation state of MnO2 is decreased.. So it gets reduced in the reaction..
While HCl is getting oxidised in the reaction (oxidation state increase) ..
Hope it helps ..

Answer 2

hey here your answer Mno2 is oxidised in Mncl2 and hcl is reduced in cl2
