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