Baking soda neutralizes acids in various circumstances, including inside the human body and in the environment. Baking soda, also known as sodium bicarbonate, is a base that cancels out the negative effects of acids.
Since baking soda is an effective acid neutralizer, it is often a component in acid reflux treatment. Sodium bicarbonate is actually produced naturally by the pancreas to assist with neutralizing acids from food, but various lifestyle decisions negatively impact the pancreas' ability to produce this helpful material. In the environment, baking soda is useful in neutralizing acids before they are poured into the sewer system, thereby preventing potentially hazardous situations.
