Question

What happens when MnO2 reacts with dilute Hydrochloric acid? Write the reaction involved? If it ids redox reaction then name the substance oxidised, reduced, oxidising agent or reducing agent. The best and complete answers will be marked brainliest

Answer 1

Answer:

Mno2+Hcl--->Mncl2+H2o........this undergoes redox reactions Mn us reduced and Cl- is oxidized

Answer 2

MnO2 + 4HCl -----------> MnCl2 + Cl2 + H2O

The oxidation state of Cl in HCL is -1 and it changes to 0 in the product Cl2. Increase in oxidation number occurs, so Cl- is oxidized.

In MnO2, Mn is +4 state and this becomes +2 in product MnCl2. So decrease of oxidation number occurs, hence Mn is reduced.

Hence, MnO2 is the oxidizing agent and HCl is the reducing agent.

Hope it helps :)
