Baking soda can't replace baking powder. Baking soda refers to pure sodium bicarbonate and contains no other ingredients. Although baking powder is made of baking soda powder, acid powder and corn flour have been added as fillers, that is, baking soda only accounts for a part of baking powder. Although baking soda powder is alkaline, baking powder on the market is neutral. Therefore, baking soda cannot replace baking powder.

Brief introduction of baking soda

Baking soda generally refers to sodium bicarbonate. Sodium bicarbonate, white fine crystal, less soluble in water than sodium carbonate. It is also an industrial chemical. Solids begin to decompose gradually above 50℃ to produce sodium carbonate, carbon dioxide and water, 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.
