Base (chemistry) Base (chemistry) In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH) ions, are slippery to the touch, can taste bitter if an alkali, change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote certain chemical reactions (base catalysis), accept protons from any proton donor or contain completely or partially displaceable OH ions. Examples of bases are the hydroxides of the alkali metals and the alkaline earth metals (NaOH, Ca(OH), etc., see alkali hydroxide and alkaline earth hydroxide). These particular substances produce hydroxide ions (OH) in aqueous solutions, and are
Paul A. D. de Maine and on the campuses of SUNY Albany, University of Mississippi, University of Illinois, UC Santa Barbara, The Pennsylvania State University and Auburn University. He was the author of 1 patent, two books, and more than 200 published scientific research articles and reports in chemistry, computational chemistry and computer science. His fields of research included spectroscopy, charge transfer complexes, solution theory, data compression, information retrieval, human-machine interfaces, expert systems and systems for detecting and correcting computational errors. Paul A. D. de Maine Paul Alexander Desmond DeMaine (October 11, 1924 – May 13, 1999) was a leading figure in the early development
