The Lewis Concept of Acidity and Basicity (or, The Electron Shell Game) By paraphrasing Brønsted slightly, we can set up the following definitions for Brønsted acids and bases: Acid- any species containing hydrogen which (as a proton) can accept a share in a pair of electrons. ...

surface basicityprobe moleculesA very general definition of acids and basis, following both Brønsted and Lewis theories, is the starting point to introduce the concept of the acid and basic strength of surface sites. The surface of an oxide is described as a bidimensional organization of acid–...

It was shown that the F-anion has weak dibasic properties1 the titration reaction being : corresponding to the solvolysis equilibrium F-+ 2~1X~ t ~12x6F-+ 2X-(21) (22) The basicity constant values are lo-3·5 and 10-4 in Na~1Cl4 and N~1Br4 1 respectively. The authors assume...
7.0. 19.2 The pH Concept A solution in which [H+] is greater than 1 10–7 M has a pH less than 7.0 and is acidic. The pH of pure water or a neutral aqueous solution is 7.0. A solution with a pH greater than 7 is basic and has a [H+] of less than 1 10–7 M...
pOH is the measure of the basicity of a substance pOH = -log[OH-] On the pOH scale Below 7 is basic 7 is neutral Above 7 is acidic pH and pOH are flip sides of the same coin They are related in that pH + pOH = 14 Find the pH, pOH, [H3O+] and [OH−] of a 1L of a...
basicity gap of 82.7 kJ·mol−1. This appar- ent contradiction moved us to investigate whether there is a significant effect of the unsaturation of the alkyl chain on these intrinsic properties. For this purpose, we have evalu- ated the gas-phase acidities and basicities of the three ...
