Which substance is added as stabiliser in storage of $H_{2} O_{2}$

Options:

Answer:

Solution:

Hydrogen peroxide ( $H_{2} O_{2}$ ) is unstable and decomposes over time. Urea is added as a stabilizer to slow down this decomposition. It forms an adduct with $H_{2} O_{2}$ , known as hydrogen peroxide-urea (HPU) or carbamide peroxide, which is more stable for storage and transport.

The decomposition reaction of hydrogen peroxide is:

$2 H_{2} O_{2} (a q) \to 2 H_{2} O (l) + O_{2} (g)$
