  2. Acid strength - Wikipedia

    en.wikipedia.org/wiki/Acid_strength

    Acid strength is the tendency of an acid, symbolised by the chemical formula, to dissociate into a proton, +, and an anion, . The dissociation or ionization of a strong acid in solution is effectively complete, except in its most concentrated solutions.

  3. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ⁠ ⁠) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction

  4. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    A strong acid, such as hydrochloric acid, at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide, at the same concentration, has a pH of 14. Since pH is a logarithmic scale, a difference of one in pH is equivalent to a tenfold difference in hydrogen ion concentration.

  5. Henderson–Hasselbalch equation - Wikipedia

    en.wikipedia.org/wiki/Henderson–Hasselbalch...

    C A is the analytical concentration of the acid and C H is the concentration the hydrogen ion that has been added to the solution. The self-dissociation of water is ignored. A quantity in square brackets, [X], represents the concentration of the chemical substance X. It is understood that the symbol H + stands for the hydrated hydronium ion.

  6. Dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Dissociation_constant

    The dissociation constant has molar units (M) and corresponds to the ligand concentration [] at which half of the proteins are occupied at equilibrium, [6] i.e., the concentration of ligand at which the concentration of protein with ligand bound [] equals the concentration of protein with no ligand bound []. The smaller the dissociation ...

  7. Leveling effect - Wikipedia

    en.wikipedia.org/wiki/Leveling_effect

    The strength of a strong acid is limited ("leveled") by the basicity of the solvent. 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:

  9. Acidity function - Wikipedia

    en.wikipedia.org/wiki/Acidity_function

    An acidity function is a measure of the acidity of a medium or solvent system, [1] [2] usually expressed in terms of its ability to donate protons to (or accept protons from) a solute (Brønsted acidity).
