Applications
Sodium carbonate is commonly used as an inorganic base and a buffer component in several synthetic organic transformations in both chemical industries and research laboratories. Often used as an electrolyte, sodium carbonate acts as a very good conductor in the process of electrolysis. Apart from being used as a common chemical/biological/biotechnological laboratory reagent, it is also used as a water softener in laundering, processing wood pulp, cleaners, and making glass. It can be used for standardization of acids, and qualitative testing of cations. In dyeing with fiber-reactive dyes, sodium carbonate is used to ensure proper chemical bonding of the dye with cellulose fibers.
