Solution Verified by Toppr Correct option is A) The potassium chromate can be prepared by chromate ore FeCr 2O 4. The various reactions given are: (i)4FeCr 2O 4 + 4Na 2CO 3 +9O 2 → 8NaCrO 4 +2Fe 2O 3 +4CO 2 (chromite ore). (ii)2Na 2CrO 4 +H 2SO 4 → Na 2Cr 2O 7 +Na 2SO 4 +H 2O (iii) 2Na 2Cr 2O 7 +2KCl → 2K 2Cr 2O 7 +2NaCl

Potassium permanganate is prepared from pyrolusite (MnO,) ore. The preparation involves the following steps. (i) Conversion of MnO(2) to potassium manganate: Powdered ore is fused with KOH in the presence of air or oxidising agents like KNO(3) . A green coloured potassium manganate is formed.
