5. Chemical change Cake batter contains baking soda (sodium bicarbonate). When Sodium bicarbonate reacts with water, it forms carbonic acid. Carbonic acid breaks down into carbon dioxide and water. The carbon dioxide causes bubbles witch makes the batter rise. When cupcakes are close to being done, the surface browns. The browning of the service is called the Maillard reaction. This happens when amino acids and sugars are heated together.
