Question

H₂O₂ is stored in wax-lined brown coloured bottles. Explain giving reasons.

Open in App

Solution

H₂O₂ gets decomposed in presence of metal surface and alkali traces (glass), to oxygen so it is stored in waxed lined glass container or plastic vessel in dark. In presence of dust cause explosion.
2 H₂O₂----> 2 H₂O + O₂
