1 has different uses. Baking soda makes cookies crisper, and Baking powder makes bread softer.
2, commonly known as different. Baking soda, sodium bicarbonate, commonly known as baking soda. Baking powder is a compound leavening agent, also known as foaming powder and baking powder.
Sodium bicarbonate, chemical formula NaHCO? Commonly known as baking soda. White fine crystals, less soluble in water than sodium carbonate. It is also an industrial chemical. Solids begin to decompose gradually to produce sodium carbonate, carbon dioxide and water above 50℃, and completely decompose at 270℃.
Sodium bicarbonate is an acid salt formed by neutralization of strong base and weak acid, and it is weakly alkaline when dissolved in water. This characteristic can make it a leavening agent in food production. Sodium bicarbonate will remain sodium carbonate after the action, and too much use will make the finished product have an alkaline taste.
Extended data:
Both yeast and baking powder have the function of fermentation, but they are essentially different.
Yeast is a pure biological bulking agent and an active microorganism, which does no harm to human body. Chemical baking powder is a chemical bulking agent, which generally refers to baking soda (sodium bicarbonate), stinky powder (ammonium bicarbonate), alum (aluminum potassium sulfate or aluminum potassium sulfate, S.A.S), baking powder and other substances.
