The chemical formula for hydrogen carbonate is HCO3.
Hydrogen carbonate, also known as bicarbonate, is a polyatomic ion with the formula HCO3−. It is the conjugate base of carbonic acid (H2CO3). Hydrogen carbonate is a common constituent of natural waters, and it is also used in a variety of industrial and commercial products, including baking soda and antacids.
Hydrogen carbonate plays an important role in acid-base balance in the body. It is a buffer, which means that it can help to maintain a constant pH level in the blood and other fluids. Hydrogen carbonate also helps to transport carbon dioxide out of the body.
Here are some examples of hydrogen carbonate compounds:
Sodium hydrogen carbonate (NaHCO3) - baking soda
Potassium hydrogen carbonate (KHCO3) - potassium bicarbonate
Calcium hydrogen carbonate (Ca(HCO3)2) - calcium bicarbonate
Magnesium hydrogen carbonate (Mg(HCO3)2) - magnesium bicarbonate
Hydrogen carbonate is a safe and non-toxic compound. It is generally well-tolerated by humans, but it can cause side effects such as diarrhea and nausea in high doses.
