The chemical formula for bicarbonate (also known as hydrogencarbonate) is HCO3-.
This represents a polyatomic anion formed during the deprotonation of carbonic acid (H2CO3). The superscript "-" indicates that the ion carries a single negative charge.
Here's a breakdown:
- H: Represents a hydrogen atom.
- C: Represents a carbon atom.
- O: Represents an oxygen atom.
- 3: Indicates that there are three oxygen atoms.
- -: Indicates that the ion has a negative charge of 1.
Bicarbonate plays a crucial role in various biological and chemical systems, including:
- pH buffering in blood: It helps maintain stable blood pH.
- Digestion: It neutralizes stomach acid in the small intestine.
- Geological processes: It is a component of many minerals and is involved in weathering.
- Industrial applications: It is used in baking powder, fire extinguishers, and other products.
In summary, HCO3- is the chemical formula that accurately describes the bicarbonate ion.
