| Summary: | The following experiments regarding the behaviour of carbonic acid in presence of different vapours above the temperature of the critical point of the pure gas, were undertaken to ascertain if any optical discontinuity could be observed in such mixtures. As the object was intentionally a qualitative investigation, many of the pressure observations have been taken with the metallic manometer. The Liquefaction of Carbonic Acid in presence of other Bodies . 1. Carbonic Acid and Bisulphide of Carbon . Carbonic acid liquefied in presence of a small quantity of bisulphide of carbon at a pressure of 49 atmospheres and a temperature of 19° C. It floated on the convex surface of the bisulphide, the line of separation being sharp and well defined. |
