Nahcolite is a soft, colourless or white carbonate mineral with the composition of sodium bicarbonate (Na H C O 3) also called thermokalite. It crystallizes in the monoclinic system. [4] Nahcolite was first described in 1928 for an occurrence in a lava tunnel at Mount Vesuvius, Italy. [2] Its name refers to the elements which compose it: Na, H ...

Nahcolite (NaHCO3), colourless to white carbonate mineral, a naturally occurring sodium bicarbonate. (The name nahcolite is formed from the chemical formula, with the suffix -lite replacing the subscript numeral 3.) Its structure consists of planar chains of carbonate groups linked by hydrogen

Nahcolite, as ordinary baking soda, is used to make cookies, cakes, biscuits, and similar pastries "rise" during baking. In the presence of an acid, it easily decomposes into carbon dioxide and a sodium salt of that acid, and the trapped bubbles provide the textures we enjoy in those foods.
