What is baking soda and how is it made?
Baking soda, also known as sodium bicarbonate, is a naturally occurring mineral composed of sodium, hydrogen, carbon, and oxygen. It is usually extracted from mineral deposits through a process known as solution mining, where hot water is pumped into underground deposits to dissolve the minerals. The resulting solution is then brought to the surface, where the baking soda is extracted through a process of crystallization.
The extracted baking soda is then refined and purified to produce a fine white powder. This powder is what is commonly used in cooking and household applications. The refining process involves removing any impurities and additives, resulting in a pure and consistent product. The final product is then packaged and distributed to stores for consumer use.
What are the different uses of baking soda?
Baking soda has a wide range of uses, from cooking and baking to household cleaning and personal care. In cooking, baking soda is often used as a leavening agent to help baked goods rise.
