Bob’s Red Mill baking soda specifically states that it is aluminum free, while Arm & Hammer baking soda does not. However, both products are pure sodium bicarbonate and contain no aluminum.

Both baking soda and baking powder are called leavening agents and are used to make baked goods rise. Baking soda must be used in a recipe that also contains some kind of acid, such as vinegar or lemon juice. The combination of the acid and the sodium bicarbonate creates the chemical reaction that produces carbon dioxide bubbles and makes the cake or bread rise. Baking powder contains an acid, so mixing it with a liquid that does not contain an acid will cause the chemical reaction to occur.
