11.What's the difference between baking powder and baking soda?Baking soda is sodium bicarbonate. It will not make cake rise. Baking powder is a mixture of tartaric acid and baking soda. When water is added, the acid and bicarbonate combine to make a salt and carbonic acid. The carbonic acid decomposes to water and carbon dioxide gas. The gas causes cakes to rise.
