| Application: | Sodium carbonate may be used as a reducing agent for the preparation of graphene sheets with good electrocapacity from graphene oxide dispersion. It may also be used in procedures for the synthesis of the following: • Biaryls via palladium-catalyzed cross-coupling reaction of phenylboronicacid with haloarenes. • Chalcones and azachalcones via aldol condensation of aldehydes with ketones in aqueous medium. • Enynes via copper-catalyzed allylation of functionalized alkynes. |
| Application: | Sodium carbonate may be used in the following studies: • Determination of total polyphenolic index of wine products from grape by the Folin-Ciocalteu method. • To compose the ELISA (Enzyme-Linked Immunosorbent Assay) coating buffer. • Preparation of the antibody coating buffer for use in IGF-I kinase receptor activation assay (KIRA) assay. |
| Biochem/physiol Actions: | Buffer component, may be used for the removal of peripheral membrane proteins. |
| General description: | Sodium carbonate (Soda) is a white salt. It can be synthesized by the electrolysis of the molten sodium hydroxide or sodium chloride. |
| General description: | Sodium carbonate is a water soluble weak base. Its aqueous solution has the ability to uptake carbon dioxide. It can also catalyze the conversion of sewage sludge to liquid fuels. |
