Question

The decomposition of H2 O2 can be prevented by-
1. Urea
2. Oxalic acid
3. Formic acid
4. KOH

Answer 1

option a Urea..........

Answer 2

Option (a) Urea is the correct answer

The decomposition of H2O2 can be prevented by Urea

Explanation for correct answer:

• Decomposition of H2O2  is prevented in the presence of acetanilide.
• Acetanilide acts as a stabilizer which when added to the solutions retards the decomposition.
• The decomposition of H2O2  can be prevented by the addition of little    H3 PO4, glycerin, acetanilide, alcohol, etc. which can act as negative catalysts or inhibitors.
• Sodium citrate is used to stabilize hydrogen peroxide.
• Conventional use of hydrogen peroxide involves the catalyzation of peroxide by the addition of a ferrous iron catalyst, resulting in a vigorous Fenton's type reaction
• It decomposes slowly on exposure to light.
• Its decomposition can be prevented by adding urea as a stabilizer.
