Definition of sodium carbonate in English: sodium carbonatenounˌsəʊdɪəm ˈkɑːbənətˌsoʊdiəm ˈkɑrbənət mass nounA white alkaline compound with many commercial applications including the manufacture of soap and glass. 碳酸钠，苏打。亦称WASHING SODA Chemical formula: Na₂CO₃ Also called washing soda Example sentencesExamples - When falling into water this ash instantly cements as sodium carbonate and, in this alkaline environment, bone apatite and calcium carbonate fossils are relatively insoluble.

- Probably the best known compound among ancient civilizations was sodium carbonate, commonly known as soda.
- At temperatures above 300°F, sodium bicarbonate decomposes into sodium carbonate (a more stable substance), water, and carbon dioxide.
- The carbonates are washed repeatedly with a dilute solution of sodium carbonate, thus removing any coloration from the precipitate.
- Common fluxes are sodium carbonate (which produces ‘soda’ glass) and potassium carbonate (which produces ‘potash’ glass).
- If more alkalinity was needed, then borax, sodium metaborate, sodium carbonate, or even lye were used.
- Ernest Rebecq Solvay invented the process of manufacturing sodium carbonate with ammoniac.
- Glass was first made from sand and sodium carbonate, found in dry lake beds around Alexandria, and later improved greatly by the addition of lime, calcium oxide.
- Diluting one part of it with 50 parts of a 0.5% solution of sodium carbonate in water makes a very good developer.
- Most of the sodium carbonate used in North America comes from large deposits of the mineral trona, a sodium carbonate / bicarbonate found in Wyoming.
- If alkaline cleaners that contain sodium carbonate are used, then the cleaners themselves must be removed prior to welding.
- Progress with dyestuffs, coal-tar compounds, and other organics accelerated after the adoption of the Solvay process, a commercial technology for the manufacture of sodium carbonate, in the 1880s.
- Heating and agitation, after the introduction of sodium carbonate, precipitated calcium carbonate, and waste material settled.
- The calcium reacted with sodium carbonate, precipitating as calcium carbonate.
- Fahey concluded that the pseudomorphs were derived when rainwater penetrating the near-surface layers leached out the sodium carbonate from the original shortite, leaving behind calcium carbonate.
- Holmes returned to his bench and quickly replaced the hydrochloric acid, sulphuric acid, and sodium carbonate to their proper storage locations.
