Baking soda (NaHCO3) is a naturally occurring crystalline chemical compound that is often found in powder form. It is mined and then created through a chemical process. Initially it comes out of...
In cooking, baking soda is primarily used in baking as a leavening agent. When it reacts with acid or is heated, carbon dioxide is released, which causes expansion of the batter and forms the characteristic texture and grain in cakes, quick breads, soda bread, and other baked and fried foods.
How did baking soda come to be discovered by the Ancient Egyptians? The Egyptians, known for their advanced understanding of science and medicine, discovered a natural deposit of sodium bicarbonate near the Nile River.
Where does baking soda come from, and is it really so eco-friendly? Advice columnist Umbra Fisk digs down to find out about the mining and manufacturing processes used to produce baking...
Baking soda, also known as sodium bicarbonate (NaHCO3), has its origins in ancient Egypt. The ancient Egyptians first discovered a natural mineral called natron, which is composed mainly of sodium bicarbonate. Natron was used by the Egyptians as a cleansing agent and for mummification.
Baking soda, or sodium bicarbonate, comes from soda ash obtained either through the Solvay process or from trona ore, a hard, crystalline material. Trona dates back 50 million years, to when the land surrounding Green River, Wyoming, was covered by a 600-square-mile (1,554-square-kilometer) lake.
Sodium bicarbonate, white crystalline or powdery solid that is a source of carbon dioxide and so is used as an ingredient in baking powders, in effervescent salts and beverages, and as a constituent of dry-chemical fire extinguishers.
Baking soda’s origin can be traced back to ancient civilizations that utilized natural sources of sodium bicarbonate for various purposes. The Ancient Egyptians, for instance, used a combination of animal fat ashes and lime to create an early version of sodium bicarbonate.
In 1846, the introduction of baking soda, a salt that can react with an acid to create carbon dioxide, made things easier. But baking soda still needed to be mixed with an acid. Since it was...
Sodium bicarbonate (chemical formula: NaHCO 3), also called baking soda, is a crystalline salt, found in a natural mineral form in nahcolite deposits. The science of baking soda has a long and interesting history.
