Potassium Ferrocyanide is stored in dark coloured bottles and kept away from sunlight
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.
