Describe the preparation of potassium permanganate from pyrolusite ore. Write balanced chemical equation for one reaction

Question 1

(i) Describe the preparation of potassium permanganate from pyrolusite ore. Write balanced chemical equation for one reaction to show the oxidizing nature of potassium permanganate.

(ii) Draw the structures of chromate and dichromate ions.

Question 2

(i) 2MnO2 + 4 KOH + O2 ----------> 2K2MnO4 + 2H2O

3MnO42- + 4H+ ------------> 2MnO4- + MnO2 + 2H2O

MnO4– + 5Fe2+ + 8H+ ⎯→ Mn2+ + 5Fe3+ + 4H2O
