laboratory manual for the detection of poisons and powerful drugs
Excerpt from the book: “Salicylic acid, or ortho-oxy benzonic acid, crystallizes in long, white needles soluble in about 500 parts of cold and in 15 parts of boiling water; and freely soluble in ethyl alcohol, either, chloroform and carbon disulphide. It has a peculiar taste which is sweetish, acidulous and rather acrid. Heated carefully, salicylic acid will sublime in five needles without decomposition. A little of the acid may show this behavior even upon the water-bath. If heated quickly, salicylic acid is decomposed in part into phenol and carbon dioxide”. The book contains bright and very detailed description of chemical substances, and it would be great for students studying chemistry of for anyone interested in this science.
