What is baking soda?

Sodium bicarbonate, commonly known as baking soda or bicarbonate of soda, is a white, odorless, crystalline solid with the formula NaHCO3. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a common ingredient in baking and cooking, where it is used as a leavening agent to cause baked goods to rise. It is also used as a cleaning agent, deodorizer, and abrasive.

In baking, sodium bicarbonate reacts with acids, such as those found in buttermilk or lemon juice, to produce carbon dioxide gas. This gas causes the batter or dough to rise, resulting in a light and fluffy texture. Sodium bicarbonate is also used as a tenderizer for meats, as it helps to break down the proteins and make them more tender.

In cleaning, sodium bicarbonate is used as a mild abrasive for removing dirt and grime. It is also effective at deodorizing surfaces and removing stains. Sodium bicarbonate is a natural cleaner that is safe for use on most surfaces, including fabrics and carpets.

Sodium bicarbonate is a versatile substance that has a variety of uses around the home. It is a safe, inexpensive, and effective cleaning agent, deodorizer, and leavening agent.
