The Theory of Acids and Bases
The Water or Arrhenius Theory was widely accepted up to the early years of this century . It defines an acid as a hydrogen compound ionizing in water to give hydrogen ions, and a base as a hy<iToxyl compound which gives hydroxide ions in water. The neutralization reaction between an acid and a base produces a salt and water only: HA(ac id) + BOH(base) ""' BA(salt) + H 20(water) and the salts so...

متن کاملThe Coulometric Titration of Acids and Bases in Dimethylsulfoxide Media
The coulometric titration of 20-200 peq of acids and bases in DMSO media is described. In the titration of bases, the electro-oxidation of hydrogen at a platinized platinum electrode is used as the source of protons. The conditions for 100 % current efficiency at this electrode are low current density to avoid passivity and regular treatment of the electrode with potassium dichromate-sulfuric a...
متن کاملThe history of blood gases, acids and bases
cross-reference between papers. Worse, editorial indulgence has left several of them substantially overlapping in scope, if not mutually contradictory-so that Nutton does much of the job of three other contributors rather more cogently than they can themselves. The weakness of these three emphasizes a more general failure to match painstaking scholarship with thoughtful interpretation. Contente...
متن کاملInvestigation of Organic Complexes of Imidazolines Based on Synthetic Oxy- and Petroleum Acids as Corrosion Inhibitors
The mixture of Synthetic Petroleum Acids (SPA) and oxyacids (OSPA) have been synthesized on the basis of naphthenic-paraffinic hydrocarbons separated from 217-349°C fractions of Azerbaijan oils in the presence of the salts of Natural Petroleum Acids (NPA). The acid number of the obtained (SPA+OSPA) was 165 mgKOH/g, the yield was 40%. Imidazoline derivatives have been synthesized based on the mi...
