Question

why some medicines are kept in dark coloured bottles

Answer 1

Because some chemicals andmedicines decompose in the presence of light .So in order to protect it , they are stored in coloured bottles. This is because some chemicals are photosensitive meaning that they break down when exposed to light. Agood example of this is Hydrogen Peroxide (H3O).

Answer 2

hey

gd aftrn

here is your answer

This is because some chemicals are photosensitive meaning that they break down when exposed to light. A good example of this is Hydrogen Peroxide (H3O). Because the bonds are unstable due  to the fact that oxygen can only bond with two other electrons when each of the Hydrogens each have one electron. Therefore the energy of the light (photons) is great enough to break it up into water and Hydrogen gas.
