Current Question (ID: 8706)

Question:
$\text{H}_2\text{O}_2 \text{ is stored in:}$
Options:
  • 1. $\text{Iron container after the addition of stabilizer}$
  • 2. $\text{Glass container after the addition of stabilizer}$
  • 3. $\text{Plastic container after the addition of stabilizer}$
  • 4. $\text{None of the above}$
Solution:
$\text{Hint: H}_2\text{O}_2 \text{ stored in a plastic container}$ $\text{The decomposition of H}_2\text{O}_2 \text{ is easily catalysed by metals, rough surfaces, sunlight, dust particles, glass and alkali.}$ $\text{It is stored in vessels of pure aluminium or in stone jars in dark.}$ $\text{Concentrated solutions of hydrogen peroxide are stored these days in polythene bottles kept in refrigerators.}$ $\text{Small amounts of stabilizers such as orthophosphoric acid, acetanilide or sodium stannate are added to the solutions to be stored.}$
