Sodium carbonate is a sodium salt of carbonic acid and a strong base. It is supplied as a white, odorless powder that is hygroscopic and very soluble in water producing a strong alkaline solution. This sodium salt can be found in the ashes of plant material but large quantities are derived from common table salt (NaCl) using the Solvay process. It is a good conductor of electricity.
Common Industrial Uses of Sodium Carbonate
A major industrial use of sodium carbonate is glass manufacturing. In this process sodium carbonate is heated with Silica and calcium carbonate to form soda lime glass, a common form of glass.
Found in many household and industrial products, the strong basic nature of sodium carbonate makes it suitable for neutralization applications. It is used in swimming pools to neutralize chlorine and as a water softener to remove ions that hinder soap’s effectiveness. Its ability to soften water for better clothes washing results is why it is often referred to as “washing soda”.
Sodium carbonate is also an effective pH regulator and is used in film developing and food applications for preserving and browning. In chemistry, it aids in the electrolysis process because of its excellent conductive properties.
