Question

Why is baking soda added to cakes​

Answer 1

Answer:

Both baking powder and baking soda are chemical leavening agents that cause batters to rise when baked. The leavener enlarges the bubbles which are already present in the batter produced through creaming of ingredients. When a recipe contains baking powder and baking soda, the baking powder does most of the leavening.
