Publisher SummaryThis chapter provides an overview of industrial alkalis that include the weak alkali ammonia, caustic soda, and lime. Lime is obtained by burning limestone and is one of the most important of all chemical commodities. It is the most economical source of alkali for many industries and agriculture. It is used in steelmaking and other metallurgical operations, in control of air pollution from smokestack gases, in water and sewage treatment, in pulp and paper production, in reduction of soil acidity, in cement and concrete manufacture, and in many chemical processes, such as papermaking. Sodium carbonate is a widely used source of mild alkali, either in hydrated form of big, glassy crystals—washing soda or as the powdery anhydrous solid—soda ash.
