Vedclass · Answer

(B) Commercially,sodium chromate $(Na_2CrO_4)$ is produced by roasting chromite ore $(FeCr_2O_4)$ with sodium carbonate $(Na_2CO_3)$ in the presence of excess air (oxygen). The chemical reaction is: $4FeCr_2O_4 + 8Na_2CO_3 + 7O_2 \rightarrow 8Na_2CrO_4 + 2Fe_2O_3 + 8CO_2$ This process converts the chromium in the ore into soluble sodium chromate.
