Bicarbonate serves a crucial biochemical role in the physiological pH buffering system.[3]
The term "bicarbonate" was coined in 1814 by the English chemist William Hyde Wollaston.[4] The prefix "bi" in "bicarbonate" comes from an outdated naming system and is based on the observation that there is twice as much carbonate (CO2−
3) per sodium ion in sodium bicarbonate (NaHCO3) and other bicarbonates than in sodium carbonate (Na2CO3) and other carbonates.[5] The name lives on as a trivial name.
