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.
Formula:
| Ingredients | Standard formula |
| Camphor | 1 gm |
| Ethyl alcohol | 2 ml |
| Purified water | 100 ml |
Preparation of Camphor Water:
- Dissolve 1 gm camphor in 2 ml ethyl alcohol.

- Filter the solution if required.
Note: Ice-cold water dissolves more camphor than water at ordinary temperature.
