2. Acid strength - Wikipedia

   en.wikipedia.org/wiki/Acid_strength

   Its conjugate base is the acetate ion with K b = 10 −14 /K a = 5.7 x 10 −10 (from the relationship K a × K b = 10 −14), which certainly does not correspond to a strong base. The conjugate of a weak acid is often a weak base and vice versa .

3. Leveling effect - Wikipedia

   en.wikipedia.org/wiki/Leveling_effect

   Similarly the strength of a strong base is leveled by the acidity of the solvent. When a strong acid is dissolved in water, it reacts with it to form hydronium ion (H 3 O +). [2] An example of this would be the following reaction, where "HA" is the strong acid: HA + H 2 O → A − + H 3 O + Any acid that is stronger than H 3 O + reacts with H ...

4. Acid–base reaction - Wikipedia

   en.wikipedia.org/wiki/Acid–base_reaction

   In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.

5. Non-nucleophilic base - Wikipedia

   en.wikipedia.org/wiki/Non-nucleophilic_base

   2,6-Di-tert-butylpyridine, a weak non-nucleophilic base [2] pK a = 3.58; Phosphazene bases, such as t-Bu-P 4 [3] Non-nucleophilic bases of high strength are usually anions. For these species, the pK a s of the conjugate acids are around 35–40. Lithium diisopropylamide (LDA), pK a = 36

6. HSAB theory - Wikipedia

   en.wikipedia.org/wiki/HSAB_theory

   HSAB is an acronym for "hard and soft (Lewis) acids and bases".HSAB is widely used in chemistry for explaining the stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species.

7. Base (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Base_(chemistry)

   A strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca(OH) 2, respectively. Due to their low solubility, some ...

8. Amphoterism - Wikipedia

   en.wikipedia.org/wiki/Amphoterism

   [7] Another possibility is the molecular autoionization reaction between two water molecules, in which one water molecule acts as an acid and another as a base. H 2 O + H 2 O ⇌ H 3 O + + HO −. The bicarbonate ion, HCO − 3, is amphoteric as it can act as either an acid or a base: As an acid, losing a proton: HCO − 3 + OH − ⇌ CO 2− ...

9. Acid–base titration - Wikipedia

   en.wikipedia.org/wiki/Acid–base_titration

   This can be used for weak bases and strong bases. [8] An example of an acidimetric titration involving a strong base is as follows: Ba(OH) 2 + 2 H + → Ba 2+ + 2 H 2 O. In this case, the strong base (Ba(OH) 2) is neutralized by the acid until all of the base has reacted. This allows the viewer to calculate the concentration of the base from ...
