Solution:
Concept- It has been discovered that baking powder is typically used to enhance the volume and lighten the texture of many baked meals. Typically, it works by expanding bubbles in the wet liquid due to an acid-base interaction, which leavens the mixture.Yeast is also substituted with baking powder in items where the fermentation flavours would be objectionable. In order to hasten the manufacture of baked goods, it is also discovered that the batter lacks the elastic structure needed to keep the gas bubbles for longer than a few minutes.
