COMEDK · Chemistry · 10. Hydrogen
Decomposition of hydrogen peroxide can be prevented by adding
- A urea
- B \(\mathrm{MnO}_2\)
- C oxalic acid
- D NaOH
Answer & Solution
Correct Answer
(A) urea
Step-by-step Solution
Detailed explanation
\(\mathrm{H}_2 \mathrm{O}_2\) decompose on exposure to light \(2 \mathrm{H}_2 \mathrm{O}_2 \longrightarrow 2 \mathrm{H}_2 \mathrm{O}+\mathrm{O}_2\) Thus, its decomposition can be prevented by adding urea as a stabiliser.
