Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 14: 1921-22 Sulphuric acid is universally concentrated by the application of heat. The first interest of the designer of apparatus to concentrate sulphuric acid must hence lie in the thermal properties of sulphuric acid. Several articles have been written on this subject, and one of them at least has treated the subject very thoroughly and comprehensively. The results, however, are not most conveniently expressed, and the original article is not particularly accessible. This, then, must be the excuse for the present attempt to present an old subject from a different viewpoint. The first thermal property of sulphuric acid which interests us is its specific heat.
