Experiments upon magnesia alba, Quicklime, and some other Alcaline Substances

"Experiments upon Magnesia Alba, Quicklime, and some other Alcaline Substances" by Joseph Black, M.D. is a scientific publication written in the mid-18th century. Authored by a prominent chemist and Professor of Chemistry at the University of Edinburgh, the book presents a thorough investigation of various alkaline substances and their properties, particularly focusing on magnesia alba and quicklime. It marks a significant contribution to the early development of modern chemistry, highlighting experimental methods and quantitative analysis. In this work, Black meticulously documents a series of experiments aimed at understanding the chemical properties and behavioral interactions of magnesia alba and quicklime with various acids and other substances. He elucidates the process of obtaining magnesia from different sources, such as epsom salt and the mother of nitre, and investigates their behavior in reactions with acids like vitriolic and nitrous acid. The experiments reveal the distinct behaviors of these alkaline substances, particularly how they absorb fixed air and their ability to interact with acids, which led Black to propose foundational ideas regarding the properties of alkaline earths. His careful documentation of these experiments not only showcases the emerging quantitative method in chemistry but also provides early insights into acid-base reactions, setting a precedent for future chemical research.
