Base (chemistry) increase the hydronium (HO) concentration in water, whereas bases reduce this concentration. A reaction between an acid and base is called neutralization. In a neutralization reaction, an aqueous solution of a base reacts with an aqueous solution of an acid to produce a solution of water and salt in which the salt separates into its component ions. If the aqueous solution is saturated with a given salt solute, any additional such salt precipitates out of the solution. The notion of a base as a concept in chemistry was first introduced by the French chemist Guillaume François Rouelle in 1754. He
Journal of Physical Chemistry A Journal of Physical Chemistry A The Journal of Physical Chemistry A is a scientific journal which reports research on the chemistry of molecules - including their dynamics, spectroscopy, kinetics, structure, bonding, and quantum chemistry. It is published weekly by the American Chemical Society. Prior to 1997 the title was simply Journal of Physical Chemistry. Owing to the ever-growing amount of research in the area, in 1997 the journal was split into "Journal of Physical Chemistry A" (molecular theoretical and experimental physical chemistry) and "Journal of Physical Chemistry B" (solid state, soft matter, liquids, etc.). Beginning in 2007, the latter underwent
