Quick Summary

An alkali lake, also known as a soda lake, is a saline lake characterized by significant amounts of sodium and potassium carbonates, along with sodium chloride, in its water. These lakes are commonly found in arid regions.1

The chemical precipitates in lake systems, including those in alkali lakes, can be various carbonates, gypsum, halite, and sulfate salts. Lakes with high concentrations of sodium sulfate are termed bitter lakes, while those with sodium carbonate are called alkali lakes. Despite their high alkalinity, some alkali lakes can support certain forms of life.2
