in mno2+4hcl ------ mncl2+ 2h2o+cl2
where is redox reaction taking place explain with the help of arrow
MnO2 + 4HCl → MnCl2 + 2H2O + Cl2
In this reaction, the oxidation number of Mn changes from +4 in MnO2 to +2 in MnCl2whereas the oxidation number of Cl changes from -1 in HCl to 0 in Cl2.
Therefore, MnO2 is reduced to MnCl2 and HCl is oxidized to Cl2.Thus, it is a redox reaction.
