Question

what is redox reactions? identify the substance Oxidised and the substance reduced;mno2+4hcl=mncl2+2h2o+cl2​

Answer 1

Answer:

C is oxidised (From C to CO2 ) . In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O , Cl (chlorine) is the substance which is oxidized from the HCl, and it is the reducing agent for the MnO2 as well.

redox reaction : The reaction in which one reactant gets oxidised and the other reactant gets reduced is called redox reaction.

Answer 2

Explanation:

The substance which gains oxygen or loses hydrogen during the reaction, it is said to be oxidised and the substance which loses oxygen or gains hydrogen during the reaction, it is said to be reduced.

MnO2 +4HCl → MnCl2 + Cl2+ 2H2O

In the following reaction HCl is oxidised to Cl2 as it loses hydrogen and MnO2 is reduced to MnCl2 as it loses oxygen.
