Calcium bicarbonate, represented by the chemical formula Ca(HCO₃)₂, is a colorless, odorless compound commonly found in nature. It is formed when carbon dioxide dissolves in water containing calcium carbonate, leading to a solution that can precipitate as solid calcium carbonate under certain conditions. This compound plays a significant role in the carbon cycle and is often present in natural water sources. In its solid form, calcium bicarbonate is not stable and typically exists in solution. It is important in various applications, including water treatment and as a buffering agent in aquatic ecosystems. Understanding its properties helps in managing water quality and maintaining ecological balance.
