Question

Hydrogen peroxide is prepared in the laboratory by: (A) passing CO2 into BaO2  (B) adding MnO2 to dil. H2SO4  (C) adding Na2O2 to cold water (D) adding PbO2 into KMnO4 .

Tardigrade Admin · Accepted Answer

Hydrogen peroxide is prepared by the action of

C O_{2}

on barium peroxide

(B a O_{2})

.

(Barium peroxide) B a O_{2} + C O_{2} + H_{2} O \to (Barium carbonate) B a C O_{3}

+ (Hydrogen peroxide) H_{2} O_{2}

Q. Hydrogen peroxide is prepared in the laboratory by:

passing $C O_{2}$ into $B a O_{2}$

adding $M n O_{2}$ to dil. $H_{2} S O_{4}$

adding $N a_{2} O_{2}$ to cold water

adding $P b O_{2}$ into $K M n O_{4}$ .

Hydrogen peroxide is prepared by the action of $C O_{2}$ on barium peroxide $(B a O_{2})$ .
$(Barium peroxide) B a O_{2} + C O_{2} + H_{2} O \to (Barium carbonate) B a C O_{3}$
$+ (Hydrogen peroxide) H_{2} O_{2}$

Q. Hydrogen peroxide is prepared in the laboratory by:

passing CO2​ into BaO2​

adding MnO2​ to dil. H2​SO4​

adding Na2​O2​ to cold water

adding PbO2​ into KMnO4​ .

Hydrogen peroxide is prepared by the action of CO2​ on barium peroxide (BaO2​) . (Barium peroxide)BaO2​​+CO2​+H2​O→(Barium carbonate)BaCO3​​ +(Hydrogen peroxide)H2​O2​​

passing $C O_{2}$ into $B a O_{2}$

adding $M n O_{2}$ to dil. $H_{2} S O_{4}$

adding $N a_{2} O_{2}$ to cold water

adding $P b O_{2}$ into $K M n O_{4}$ .

Hydrogen peroxide is prepared by the action of $C O_{2}$ on barium peroxide $(B a O_{2})$ .
$(Barium peroxide) B a O_{2} + C O_{2} + H_{2} O \to (Barium carbonate) B a C O_{3}$
$+ (Hydrogen peroxide) H_{2} O_{2}$
