HCO3- (bicarbonate ion)

Bicarbonate (HCO3-) is a chemical compound that plays a crucial role in maintaining the pH balance in our bodies and the environment. It acts as a buffer, helping to neutralize acids and bases, thereby preventing extreme changes in acidity. Bicarbonate is produced in the body and is also found in common substances like baking soda. In our blood, it helps transport carbon dioxide (a waste product) away from tissues, contributing to respiratory function. Bicarbonate levels are monitored in medical settings because imbalances can indicate health issues like respiratory or metabolic disorders.
