PRODUCT DESCRIPTION
Use and Manufacturing
1 DefinitionBaking soda: A white solid formed either by passing an excessof carbon dioxide through sodium carbonateor hydroxide solution, or byprecipitation when cold concentrated solutionsof sodium chloride and ammoniumhydrogencarbonate are mixed. Sodium hydrogencarbonatedecomposes on heatingto give sodium carbonate, carbon dioxide,and water. With dilute acids, it yields carbondioxide. It is used as a constituent ofbaking powder, in effervescent beverages,and in fire extinguishers. Its aqueous solutionsare alkaline as a result of salt hydrolysis.Sodium hydrogencarbonate formsmonoclinic crystals.
2 Purification MethodsCrystallise it from hot water (6mL/g). The solid should not be heated above 40o due to the formation of carbonate.
3 Usage
In manufacture of many sodium salts, source of carbon dioxide, in effervescent salts, beverages, cleaning compound.
