Bicarbonate of soda replacement

On this Wikipedia the language bicarbonate of soda replacement are at the top of the page across from the article title. For baking soda, see sodium bicarbonate. For the programming principle, see Tim Toady Bicarbonate. Not to be confused with Dicarbonate.

For the oxoacid, see carbonic acid. For the gas, see water gas. Bicarbonate serves a crucial biochemical role in the physiological pH buffering system. The term “bicarbonate” was coined in 1814 by the English chemist William Hyde Wollaston. The name lives on as a trivial name.

The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. A bicarbonate salt forms when a positively charged ion attaches to the negatively charged oxygen atoms of the ion, forming an ionic compound. It is then carried to the lung, where the reverse reaction occurs and CO2 gas is released. Additionally, bicarbonate plays a key role in the digestive system. It raises the internal pH of the stomach, after highly acidic digestive juices have finished in their digestion of food. Bicarbonate also acts to regulate pH in the small intestine.
