In practice, the amount of alcohol in a preparation is generally referred to in terms of per cent by volume. Certain regulations in pharmaceutical practice state that the per cent of alcohol always means "by volume," unless expressed in terms by weight. As ethyl alcohol U. S. P. varies somewhat in water content, generally from 94 to 95 per cent by volume, it is impossible to give a definite formula for preparing alcohol 70 per cent by weight. Probably the best method would be to add approximately 25 cc. of water to 100 cc. of alcohol and adjusting the mixture so that the specific gravity at a temperature of 25 C. is 0.8658. A stock solution may be checked by determining the specific gravity. Alcoholometric tables appear in many books of analysis, and an official table appears in the U. S. P. XI. A Westphal balance, or a well graduated hydrometer, is satisfactory for determining specific gravity.
