Sodium bicarbonate n. A white crystalline substance, HNaCO3, with a slight alkaline taste resembling that of sodium carbonate. It is found in many mineral springs and also produced artificially,. It is used in cookery, in baking powders, and as a source of carbonic acid gas (carbon dioxide) for soda water. Called also baking soda, cooking soda, bicarbonate of soda, bicarb, saleratus, and technically, acid sodium carbonate, sodium acid carbonate, primary sodium carbonate, sodium dicarbonate, etc.
... for acid solutions has been the subject of much controversy. The work of Lunge (!Ztschr. angew. Chem.! (1904), 8, 231), Ferguson (!J. Soc. Chem. Ind.! (1905), 24, 784), and others, seems to indicate that the best standard is sodium carbonate prepared from sodium bicarbonate by heating the latter at temperature between 270 deg. and 300 deg.C. The bicarbonate is easily prepared in a pure state, and at the temperatures named the decomposition takes place according to ... — An Introductory Course of Quantitative Chemical Analysis - With Explanatory Notes • Henry P.

... Salt is by all odds the most important sodium compound. Next to it come the so-called carbonates: first, sodium carbonate, which is already familiar to us as washing soda; and second, sodium bicarbonate, which is an ingredient of baking powders. These are both obtained from sodium chloride by relatively simple means; that is, by treating salt with the base, ammonia, and ... — General Science • Bertha M. Clark Read full book for free!
