Q. Show the Extraction of Oxygen?
Oxygen is separated from air on a large scale by the fractional distillation of liquid air. It is obtained as a by-product along with hydrogen during electrolysis of water for the manufacture of heavy water ordinary water H2Oelectolyses faster with the result that residual water is richer in D2O. In laboratory O2can be prepared by thermal decomposition of KCIO3 in presence of MnO2 as a catalyst:
