Some of the' properties of this acid are, 1. In the elastic state it is destructive of combustion, and of animal life- it has a pungent smell, somewhat like muriatic acid, and not less suffocating- its specific gravity has not been accurately obtained- but from some experiments I have made, it seems to be extremely heavy when obtained in glass vessels- in fact, it is in that case a superfluate of silica: Into a clean dry flask, I sent a quantity of fluoric acid gas- after some time, the mixture of common air and acid was corked, and the flask weighed: it had acquired 12 grains. The flask was next inverted in water, to see how much would be absorbed, and that quantity was taken for the acid gas. The capacity of the flask was 26 cubic inches, containing originally 8.2 grains of common air- 12 cubic inches of acid gas had entered. According to this, if the whole flask had been filled with the gas, it would have gained 26 grains- consequently, 26 cubic inches of the acid gas would weigh 34.2 grains, and its specific gravity be 4.17 times that of common air. This experiment was repeated with a proportional result. The flask became partially lined with a thin, dry film of fluate of silica during the operation, which no doubt contributed something to the weight- but I am convinced, from other experiments, that this gas, when loaden with silica, is heavier than most others. A tube, four tenths of an inch in diameter, and 10 inches long, being filled with this acid gas, and inverted for one minute, retained only iVths of the gas- whereas, with carbonic acid ga... show more
