And the chemical reaction is as follows 2 2 2 3 2 2 BaO H O CO BaCO H O -> . 127. Peroxodisulphate, on hydrolysis yields (a) water (b) dihydrogen (c) hydrogen peroxide (d) deuterium 128. Which of the following is not a process of preparation of hydrogen peroxide ? (a) Auto-oxidation of 2-ethylanthraquinol (b) By passing oxygen through boiling water (c) By oxidation of isopropyl alcohol (d) By reaction of barium peroxide with dil. H2SO4. By p
