For example, it was found in the mineral natron at the bottom of dry lakes in Egypt when ancient people use it for the preparation of mummies. Like baking soda or sodium bicarbonate (NaHCO 3), soda ash It can be found naturally in arid regions as mineral deposits when water evaporates from the lakes due to the result of seasonal evaporation. Soda ash (Na 2CO 3) is soluble in the water. For example, it is produced by the reaction of sodium chloride with limestone. The production of soda ash is different from baking soda. These ashes were different from the ashes of wood due to the presence of sodium. The origin of the name soda ash gets from its extraction from the ashes of plants that grow in sodium-rich soil. Soda ash or sodium carbonate (Na 2CO 3) is commonly known as washing soda and soda crystals. It is used in the production of bakery products It is used in the production of glass, paper, soap, borax, etc The value of Mohs hardness of baking soda is 2.5
The value of Mohs hardness for soda ash is 1.3 It has only a monoclinic crystal structure The crystal structure of soda ash can be monoclinic and orthorhombic Chemical formula of baking soda is NaHCO 3
