Requirement-

Chemical-Camphor, ethanol, purified water.

Apparatus- pipette, beaker, funnel, vol. flask, measuring  cylinder.

Theory: Camphor is a ketone, obtained from Cinnamomumcamphora. It is colorless or white crystal granules or crystalline masses. It is highly volatile in nature at room temperature and readily burns with a bright smoky flame. It is soluble in 800 parts of water and 1 part of ethanol in the preparation of aromatic water ethanol acts as distributing agent. Water cannot be added in alcoholic solution of camphor because if whole camphor is precipitated then it becomes difficult to re-dissolved it by shaking the solution.

Procedure:

·         All the apparatus were thoroughly washed and dried.

·         All the ingredients were weighed accurately.

·         Required quantity of camphor was dissolved with ethanol and the resulting solution was added in purified water in a conical flask by vigorous shaking.

·         Shaking was continued until the camphor was dissolved.

·         Then filtered solution transferred in a clean tightly closed container with proper labeling.

Requirement-

Chemical-chloroform,

Apparatus- pipette, beaker 100 ml, funnel, vol. flask, measuring cylinder.

Theory: Chloroform water is a category of aromatic water. Chloroform is a clear, odorless, mobile liquid and has burning sweet taste. Specific gravity of chloroform is between 1.474 to 1.478. Proper handling of chloroform is must because in presence of flame or light it produced harmful gases like hydrogen chloride and phosgene gas. The small amount of ethanol in chloroform is retards the formation of carbonyl chloride (COCl2). It is rarely used as an inhalation anesthetic due to its serious side effect on heart and liver. Internally it is used as carminative and externally as an irritant. In the preparation of chloroform water vigorous shaking is necessary to sub divided the chloroform in small globules to exchange the solubility.

Procedure:

·         All the apparatus were thoroughly washed and dried.

·         All the ingredients were weighed accurately.

·         Required quantity of chloroform was mixed with purified water in a conical flask by vigorous shaking.

·         This semi-saturated solution transferred in a clean amber color tightly closed container with proper labeling.
