carbonate ions

Carbonate ions are chemical species made up of one carbon atom and three oxygen atoms, represented as CO₃²⁻. They carry a negative two charge because they have two more electrons than protons. Carbonate ions play a crucial role in various natural processes, such as the formation of rocks like limestone and in the ocean, where they help regulate pH levels. They are also important in biology and can be found in many household products, such as baking soda. Overall, carbonate ions are essential for environmental balance and various chemical reactions.
