Synopsis
Select Methods In Chemical Analysis. (Chiefly Inorganic) by William Crookes. This laboratory manual surveys a broad spectrum of quantitative inorganic analysis, detailing procedures for sulfur, phosphorus, nitrogen, halogens (iodine, bromine, chlorine, fluorine), cyanogen, and carbon-related materials, with extensive coal analysis and coal-gas sulfurometry. The text emphasizes accuracy, control of interferences, and practical lab technique, presenting stepwise gravimetric, volumetric, and precipitation-based methods, purification steps, and apparatus configurations. It covers sulfuric acid determination, multiple phosphoric acid processes (tin, magnesium, uranium, bismuth, lead), nitrogen estimation by combustion and evolution methods, and the determination of nitrite/nitrate with chromic oxide or chloride tests, among others. Iodine, bromine, chlorine, fluorine, and cyanogen analyses are described with purification, separation, and detection strategies; carbon, boron, silicon, and silicate chemistry are treated via wet and dry decomposition, calcimeter techniques, and silica separations. The volume also details blowpipe analysis, gas analysis, and practical apparatus design, with interferences and purification emphasized to ensure reliable results across agricultural, mining, fertilizer, water, and industrial contexts.
