The chemical name for baking soda: The chemical name for baking soda is sodium bicarbonate and can also be known as NaCOH3
What baking powder contains: Baking powder contains sodium bicarbonate, cream of tartar (potassium bitartrate) and a starch filler which is added to make sure the baking powder absorbs moisture
How baking powder works: Baking powder is a double-acting agent which means it reacts to liquid and heat and happens in two stages (can also stand for a few minutes unlike single-acting agents). The first reaction takes place when you add baking powder to the batter and it is dampened with water or milk. One of the acid salts responds to the baking soda and forms carbon dioxide. The second and last reaction takes place when the mixture is placed in the oven. The gas cells expand causing the batter to enlarge. The two stages help by making the batter able to stand for about 15-20 minutes without its leavening power being lost.
How baking soda works: When moisture is added to the batter, an acidic component (for example: yoghurt, chocolate, buttermilk or honey etc.) The chemical reaction that results is the production of bubbles of carbon dioxide which widen

    How baking soda works: When moisture is added to the batter, an acidic component (for example: yoghurt, chocolate, buttermilk or honey etc.) The chemical reaction that results is the production of bubbles of carbon dioxide which widen under oven temperatures causing the baked product to grow in size. Baking soda is a single-agent which means that the chemical reaction begins immediately when the ingredients are added so recipes with baking soda have to be made immediately or they will become useless and become flat.…

    "Over one hundred and fifty years ago, in 1846, two natives of New England took the first step toward establishing an industry that has since become of national importance. Baking soda, which is a trade name for bicarbonate of soda, is now found in practically every kitchen throughout the country and is regarded a necessity by millions of Americans. It was first prepared for commercial distribution by two early New Englanders, John Dwight of Massachusetts and his brother-in-law, Dr. Austin Church of Connecticut. Today the use of bicarbonate of soda is no longer confined to the kitchen. It is used throughout the house, in every phase of housekeeping and personal hygiene.
