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.
