The carbonate double layer

The carbonate double layer refers to a structure that forms at the interface of a solid surface and a liquid, often in environments where carbonate minerals are present, like soils or water bodies. It consists of two layers: one attracted to the solid surface and another made up of ions in the liquid, such as calcium and bicarbonate. This arrangement influences how substances interact at that interface, affecting processes like mineral stability, environmental chemistry, and biological functions. Understanding this layer is important in fields like geochemistry, environmental science, and soil science.
