The term "baking soda" can indeed be a bit misleading because it suggests that its primary use is for baking. However, baking soda is a versatile ingredient that has various applications beyond baking. The name "baking soda" originated from its historical and predominant use as a leavening agent in baking recipes.
Baking soda, also known as sodium bicarbonate (chemical formula NaHCO3), is a white crystalline powder. When it comes into contact with acidic ingredients such as vinegar, lemon juice, or buttermilk, it produces carbon dioxide gas, causing dough or batter to rise. This release of carbon dioxide creates air pockets, resulting in a lighter texture in baked goods.
Although baking soda is commonly used for baking, it also has numerous non-culinary uses. It is a popular ingredient in cleaning products, toothpaste, deodorants, and even as a home remedy for certain ailments. In these applications, baking soda's ability to neutralize odors, absorb moisture, and act as a gentle abrasive makes it useful beyond the realm of baking.
So, while the name "baking soda" may not fully reflect its versatility, it has retained the name due to its historical association with baking and leavening.
