Use of baking soda:
1) It acts to neutralize acids and break down proteins. This quality accounts for its usefulness as a tenderizer and a leaven. The
most common practical use for baking soda is as a leavening agent in baking.
2) It is baking soda’s neutralizing action on acidic scent molecules that makes it an effective deodorizer. Added to the water when
doing laundry, baking soda stabilizes the pH level, enhancing the detergent’s effectiveness.
3) Baking soda may also be added to swimming pool water to balance the pH and keep the water clear.
