One of the biggest users of oxygen today is the steel industry. Modern techniques for the manufacture of steel from pig iron depends on the efficient removal of impurities from pig iron by oxidation, In the modern converters, oxygen is passed into, or over

the molten iron as required, Oxygen for stee works is bought in the liquid form, by the ton, as is known as "Lonnage" oxygen.

(a) (xygen will react very slowly, under ordinary conditions with sulphur dioxide to form

It will be found that the weight of manganese dioxide is the same as that used at the beginning of the experiment. Name of the manganese dioxide itself decomposed to evolve oxygen. It simply served as a catalyst in the decomposition of potassium chlorate.
