Vedclass · Answer

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

Fusion of $MnO_2$ with $KOH$ in the presence of air or an oxidizing agent like $KNO_3$ forms a colored compound. Identify the product and its color.
