Baking soda or sodium bicarbonate is a chemical compound that is a white solid crystalline, but often appears as a fine powder. It has an alkaline and salty taste.
The ancient Egyptians used natural deposits of sodium bicarbonate creating a paint for their hieroglyphics.
In 1846, John Dwight and Austin Church, two bakers from New York established the first factory developing baking soda.
Baking soda is used for all sorts of things, from cooking to cleaning, toothpaste, deodorant, shampoo and even medicinal practices.
