Vedclass · Answer

(B) $H_2O_2$ is a peroxide. For its preparation,we require a peroxide source.$1$. $BaO_2 + H_2SO_4 \rightarrow BaSO_4 + H_2O_2$ (This is a standard method).$2$. $PbO_2$ is a dioxide,not a peroxide. The reaction $PbO_2 + H_2SO_4 \rightarrow PbSO_4 + H_2O + \frac{1}{2}O_2$ does not produce $H_2O_2$.$3$. Aerial oxidation of $2$-ethyl anthraquinol is the industrial process for $H_2O_2$ production.$4$. Electrolysis of $(NH_4)_2SO_4$ produces ammonium peroxodisulphate,which on hydrolysis yields $H_2O_2$.

By which of the following methods,$H_2O_2$ cannot be synthesized?
