Sodium bicarbonate - Wikipedia
Sodium bicarbonate is produced industrially from sodium carbonate: Na2CO3 + CO2 + H2O → 2 NaHCO3It is produced on the scale of about 100,000 tonnes/year (as of 2001) with a worldwide production capacity of 2.4 million tonnes per year (as of 2002). Commercial quantities of baking soda are also produced by a similar method: soda ash, mined in the form of the ore trona, is dissolved in
