What is the product of the reaction between chromite ore, sodium carbonate, and oxygen?

Options

  1. ASodium chromate
  2. BPotassium dichromate
  3. CSodium dichromate
  4. DSodium chromite

Correct answer

C. Sodium dichromate

Step-by-step solution

4 FeCr 2 O 4 (chromite ore)+ 8 Na 2 CO 3 (sodium carbonate)+ 7 O 2 → 8 Na 2 CrO 4 (sodium dichromate) + 2 Fe 2 O 3 + 8 CO 2 .
