About this book
Newell’s textbook introduces practical chemistry for students, joining explanations of formulas and reactions to exercises, industrial uses, and descriptions of equipment. When it calculates sulphuric acid’s formula, percentages of hydrogen, sulphur, and oxygen become whole-number atomic ratios, making the step from measurement to notation clear. Its account of sulphuric acid also connects classroom chemistry with fertilizer production, petroleum refining, dyes, and metalwork. In the calcium chapter, a sketch and operating figures show how gases and solids move through a continuous limekiln.
