Question

HCl is added to following oxides. Which one would give $H_2{O}_2$?

• A. MnO₂
• B. PbO₂
• C. BaO
• D. None of these

Answer 1

The correct option is D

None of these

$Mn{O}_2$,$Pb{O}_2$ and $BaO$ will not give $H_2{O}_2$​ with $HCl$.

$Mn{O}_2$ and $Pb{O}_2$ will give $C{l}_2$ and $BaO$ will react with $HCl$ to give $BaC{l}_2$ and water.
