Preparation of Camphor Water

Aim: To prepare and submit 100 ml of Camphor Water as I.P. 

Requirements: Camphor, Distilled water, Beaker, Pipette, Glass rod, Measuring cylinder, etc. 

Theory: Camphor [C10H16O], is a ketone or a keto-tetrahydro-cymene, obtained from the camphor tree, Cinnamomum camphora. The solubility of camphor is only 1:700 in water, but it is freely soluble in alcohol. That is why here alcohol is used as a cosolvent. Camphor is volatile, so camphor water should be stored in a well-closed container to prevent the volatilization of camphor.
