‘Holmes returned to his bench and quickly replaced the hydrochloric acid, sulphuric acid, and sodium carbonate to their proper storage locations.’
‘Heating and agitation, after the introduction of sodium carbonate, precipitated calcium carbonate, and waste material settled.’
‘At temperatures above 300°F, sodium bicarbonate decomposes into sodium carbonate (a more stable substance), water, and carbon dioxide.’
‘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.’
‘The calcium reacted with sodium carbonate, precipitating as calcium carbonate.’
‘This solution is neutralized with sodium carbonate.’
‘Probably the best known compound among ancient civilizations was sodium carbonate, commonly known as soda.’
‘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.’
‘If more alkalinity was needed, then borax, sodium metaborate, sodium carbonate, or even lye were used.’
‘Late in the dry season of central Africa, blooms of red algae grow in expansive mats over a white crust of sodium carbonate on Tanzania's Lake Natron.’
‘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).’
‘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.’
‘Ernest Rebecq Solvay invented the process of manufacturing sodium carbonate with ammoniac.’
‘Diluting one part of it with 50 parts of a 0.5% solution of sodium carbonate in water makes a very good developer.’
‘Of particular interest is the remarkable Oldoinyo Lengai volcano of northern Tanzania, in which carbonatitic lavas composed almost entirely of sodium carbonate can frequently be seen erupting.’
‘Most of the sodium carbonate used in North America comes from large deposits of the mineral trona, a sodium carbonate / bicarbonate found in Wyoming.’
‘I mix two teaspoons of sodium carbonate to a quart of water.’
‘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.’
