What is gases form in baking?

Baking soda (sodium bicarbonate) and baking powder are chemical leavening agents that release carbon dioxide gas when mixed with liquids in the presence of heat. This gas causes baked goods to rise.

- Baking soda is a base, and it reacts with acids to produce carbon dioxide gas. This means that baking soda can only be used in recipes that contain an acidic ingredient, such as buttermilk, yogurt, honey, or lemon juice.

- Baking powder is a combination of baking soda, an acid, and a drying agent. The drying agent helps to keep the baking powder from becoming clumpy. Baking powder can be used in recipes that do not contain an acidic ingredient.
