Question

Potassium ferrocyanide is stored in dark coloured bottles and kept away from sunlight because:

• A. undergoes displacement in sunlight
• B. dark colors of the bottles absorb a lot of energy from light
• C. undergoes decomposition in sunlight
• D. evaporates in sunlight

Answer 1

Answer: (B), (C)

dark colors of the bottles absorb a lot of energy from light
undergoes decomposition in sunlight

• Potassium Ferrocyanide gets decomposed when exposed to bright light.
• The dark colours of the bottles absorb a lot of energy from the light passing through it.
• If stored in dark coloured bottles, it does not get enough light energy to decompose.
• Hence, potassium ferrocyanide is stored in dark coloured bottles and kept away from sunlight to prevent its decomposition.
