WebSoda ash, also known as c odium carbonate, is an inorganic compound with the chemical formula Na2CO3.The classification belongs to salts, not bases. Total ash content is a useful parameter of the nutritional value of some foods and feeds. Moisture can determine the aesthetics of food, giving estimates to product shelf life regardless of sample properties in a wet or dry state. Equally important in the evaluation of crude drugs, is the ash value and acid insoluble ash value determination. As per BIS standards, A tea must contain 4 to 8% (by mass) total ash and minimum 40% of which must be (water soluble ash in spent tea, however, the ash drops) below 3% and the ash itself is high in calcium. It is measured by converting the mineral constituents to the respective oxides at 800C. Why do we measure water soluble and insoluble ash?
