Question

How is baking soda prepared? State the chemical properties on which the following uses of baking soda are based:
a) as an antacid

Answer 1

Explanation:

Baking soda is commercially produced through the following process: Synthesis: sodium carbonate solution is treated with carbon dioxide to form a slurry/suspension. Filtering: the suspension is separated from the liquid, producing a cake. Washing: the cake is washed in a bicarbonate solution. Antacid - NaHCO₃ acts like an absorbable antacid. Baking soda imitates the action of natural sodium bicarbonate in the body and neutralizes the stomach acid relieving acid reflux. When it is expelled, a reaction in between the contents of the soda-acid occurs which releases carbon dioxide that extinguishes the fire.
