Bicarbonates of Sodium
Sodium bicarbonate (NaHCO3), or sodium hydrogen carbonate, also known as baking soda and bicarbonate of soda, is a soluble white anhydrous or crystalline chemical compound, with a slight alkaline taste resembling that of sodium carbonate. It is found in many mineral springs and also produced artificially. It is also used as an antacid to treat acid indigestion and heartburn. The anhydrous form is also used to absorb moisture and odours; an open box can be left in a refrigerator for this purpose. Additionally, a paste from baking soda can be very effective when used in cleaning and scrubbing. Used in toothpaste, baking soda helps to gently remove stains, whiten teeth, and freshen breath.
