10 sty 2021 · To identify the strongest base we can determine their weakest conjugate acid. The conjugate acids of CH − 3, NH − 2, and S − 2 are CH4, NH3, and HS −, respectively. Next, we consider that acidity increases with positive charge on the molecule, thus ruling out that S − 2 is the weakest base.

Key Concepts and Summary. A Lewis acid is a species that can accept an electron pair, whereas a Lewis base has an electron pair available for donation to a Lewis acid. Complex ions are examples of Lewis acid-base adducts and comprise central metal atoms or ions acting as Lewis acids bonded to molecules or ions called ligands that act as Lewis ...

Give an example of a Lewis acid-base reaction that does not involve protons. Write equations illustrating the behavior of a given non-aqueous acid-base system.
Examples of the Lewis Acid-Base Reactions. In the Lewis acid-base complexation reaction, these two entities (an acid and a base) come together, resulting in a more substantial molecule.
10 sty 2021 · Amphiprotic species may either gain or lose a proton in a chemical reaction, thus acting as a base or an acid. An example is H 2 O. As an acid: \(\ce{H2O}(aq) + \ce{NH3}(aq) \rightleftharpoons \ce{NH4+}(aq) + \ce{OH-}(aq)\). As a base: \(\ce{H2O}(aq) + \ce{HCl}(aq) \rightleftharpoons \ce{H3O+}(aq) + \ce{Cl-}(aq)\)
