Which of the following can be used to prevent the decomposition of H₂O₂?

(A)Urea✓ Correct
(B)Formaldehyde
(C)Formic acid
(D)Ethanol

Answer: (A)

Solution

Hydrogen peroxide (H₂O₂) is unstable and decomposes into water and oxygen. To prevent this decomposition during storage, stabilizers are added. Urea acts as a stabilizer for H₂O₂ by forming hydrogen bonds and preventing catalytic decomposition.
