Vedclass · Answer

(B) The fusion of manganese dioxide $(MnO_2)$ with potassium hydroxide $(KOH)$ in the presence of air (or an oxidizing agent like $KNO_3$) results in the formation of potassium manganate $(K_2MnO_4)$.The chemical equation is: $2MnO_2 + 4KOH + O_2 \rightarrow 2K_2MnO_4 + 2H_2O$.Potassium manganate $(K_2MnO_4)$ is known for its characteristic dark green color.

When $MnO_2$ is fused with solid $KOH$ in the presence of air,what is the product formed and its color?
