Which of the following can reduce decomposition of H 2 O 2 on exposure to light

Options

  1. AUrea
  2. BAlkali
  3. CGlass containers
  4. DDust

Correct answer

A. Urea

Step-by-step solution

H 2 O 2 decomposes on exposure to sunlight or on heating. It also decomposes on standing but at a slow rate. These reactions occur explosively when H 2 O 2 is in contact with dust. Urea acts as a negative catalyst to this reaction and slow down the decomposition of hydrogen peroxide.
