Baking soda is also known by its chemist term: sodium bicarbonate. When heated, this compound forms carbon dioxide gas - making your breads and cookies rise.When heated, sodium bicarbonate also produces sodium carbonate, which doesn't taste so great. It leaves an unpleasant, alkaline flavor behind. But if you mix baking soda with a lemon juice or another citric carrier then the sodium carbonate is partially neutralized and leaves behind less aftertaste.FSSAI's Initiative on Safe & Nutritious Food.
