What will rises more baking powder or soda?

Baking powder is a mixture of baking soda, an acid, and a cornstarch filler. When baking powder is mixed with water, the acid reacts with the baking soda to release carbon dioxide gas. This gas causes the baked good to rise.

Baking soda is a base. It does not react with acids to release carbon dioxide gas. However, baking soda can be used as a leavening agent if it is mixed with an acid, such as vinegar or lemon juice.
