Which of the following oxides is used as a catalyst in the production of sulfuric acid and in the removal of sulfur from petroleum products?
Iron(II) oxide
Zinc oxide
Vanadium(V) oxide
Magnesium oxide
Option C Vanadium(V) oxide, which is commonly used as a catalyst in the Contact Process for the production of sulfuric acid. The vanadium oxide promotes the oxidation of sulfur dioxide to sulfur trioxide, which is then used to produce sulfuric acid. Vanadium oxide is also used as a catalyst in the hydrotreating process, which removes sulfur from petroleum products.
Explanation of incorrect option
incorrect option A Iron(II) oxide is used as a pigment in paints and as a catalyst in the Haber Process for the production of ammonia.
incorrect option B Zinc oxide is used in the production of rubber, as a component in cosmetics, and as a dietary supplement.
incorrect option D Magnesium oxide is used as an antacid to relieve heartburn and indigestion, as a laxative, and as a component in some types of cement.
