Carbonates are chemical compounds that contain the carbonate ion, which is made up of one carbon atom and three oxygen atoms (CO₃²⁻). They are commonly found in nature and play a significant role in various geological processes. For example, minerals like calcite and dolomite are important carbonate minerals that form from the accumulation of organic materials and the precipitation of calcium carbonate in water. In addition to their geological significance, carbonates are also essential in everyday life. They are used in products like baking soda and antacids, helping to neutralize acids in our bodies. Furthermore, carbonates are involved in the carbon cycle, which is crucial for regulating Earth's climate and supporting life.
