Where does Baking soda come from?

Answer 1

The baking soda we use for cooking is all made artificially. You add salt (sodium chloride) and limestone (calcium carbonate) in ammonia- the limestone is there to produce CO2 gas.

In neutral or basic solutions, sodium bicarbonate is less water-soluble than sodium chloride. When carbon dioxide passes through a concentrated solution of sodium chloride and ammonia, sodium bicarbonate precipitates according to the following chemical reaction:

NaCl + CO2 + NH3 + H2O ---> NaHCO3 + NH4Cl

The ammonia is necessary to buffer the solution at basic pH. Without it, a hydrochloric acid byproduct would render the solution acidic, and in acidic solutions, the reaction cannot proceed. In industrial practice, the reaction is carried out by passing concentrated salt water through two towers. In the first, ammonia bubbles up through the brine and is absorbed by it. It the second, carbon dioxide bubbles up through the brine and precipitates sodium bicarbonate The baking soda we use for cooking is all made artificially.

Answer 2

Baking soda, also known as sodium bicarbonate, is a naturally occurring compound that can be found in minerals called nahcolite and trona. These minerals are mined in various locations around the world, including the United States, Botswana, and Turkey. Once extracted, the mineral is processed to create the white, powdery substance known as baking soda.
