$\qquad\qquad\underline{\textsf{\textbf{ \color{magenta}{AnSwEr} }}}$

a. Here HCl is oxidized to Cl2 and Mno2 is reduced to MnCl2.

b. The reaction in which oxygen is either gained or hydrogen is lost by a substance is called oxidation reaction.

The reaction in which hydrogen is gained or oxygen is lost by a substance is called reduction reaction.

Answer 2

Answer:

1. 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. As Cl is the oxidized substance in HCl, thus it is the oxidizing agent in the reaction
