Application: Sodium carbonate can be used:
• As a catalyst in the aldol condensation of aldehydes with ketones in the synthesis of chalcone and azachalcone.
• As a pH stabilizer agent in the synthesis of FeO-NPs (iron oxide nanoparticles) in the presence of cymbopogon citratus as a reducing agent.
• As a base in the Pd-catalyzed Suzuki coupling reactions.
• As a base in the transition metal free Suzuki coupling reaction of aryl halides and arylboronic acids to form biaryls using water as a solvent and TBAB (tetrabutylammonium bromide) as a phase-transfer catalyst.

Biochem/physiol Actions: Buffer component, may be used for the removal of peripheral membrane proteins.
General description: Sodium carbonate (soda ash) is an inorganic chemical compound. It is used in the synthesis of chemicals, detergent formulations, flue gas desulfurization, and paper and pulp production.
