Which of the following can reduce decomposition of H2O2 on exposure to light (A) Alkali (B) Dust (C) — JEE Mains Chemistry Past Papers Chemistry Question

💡 Solution & Explanation

H2O2 decomposes slowly on exposure to light. 2H2O2 (l)  2H2O (l) + O2 (g) In the presence of metal surfaces or traces of alkali (present in glass containers), the above reaction is catalysed. It is, therefore, stored in wax-lined glass or plastic vessels in dark. Urea can be added as a stabiliser. It is kept away from dust because dust can induce explosive decomposition of the compound | JEE(Main) 2023 | DATE : 08-04-2023 (SHIFT-2) | PAPER-1 | CHEMISTRY PAGE # 2
