According to strictly balanced industrial reaction pathways, which of the following chemical steps a — d and f Block Elements Chemistry Question

💡 Solution & Explanation

The commercial preparation of $KMnO_4$ involves two major steps. Step 1: Oxidative fusion of pyrolusite ore ($MnO_2$) with $KOH$ and an oxidizing agent ($O_2$ or $KNO_3$) to yield the dark green manganate ($K_2MnO_4$). Step 2: Oxidation of the manganate to permanganate. This can be done chemically by bubbling $Cl_2$ or $O_3$ through the solution, or commercially via electrolytic oxidation at the anode.
