  2. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    For example, pK a for HClO is 7.2, for HClO 2 is 2.0, for HClO 3 is −1 and HClO 4 is a strong acid (pK a0). [7] The increased acidity on adding an oxo group is due to stabilization of the conjugate base by delocalization of its negative charge over an additional oxygen atom. [ 47 ]

  3. Acid strength - Wikipedia

    en.wikipedia.org/wiki/Acid_strength

    When the acidic medium in question is a dilute aqueous solution, the is approximately equal to the pH value, which is a negative logarithm of the concentration of aqueous + in solution. The pH of a simple solution of an acid in water is determined by both K a {\displaystyle K_{{\ce {a}}}} and the acid concentration.

  4. Henderson–Hasselbalch equation - Wikipedia

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

    In chemistry and biochemistry, the Henderson–Hasselbalch equation = + ⁡ ([] []) relates the pH of a chemical solution of a weak acid to the numerical value of the acid dissociation constant, K a, of acid and the ratio of the concentrations, [] [] of the acid and its conjugate base in an equilibrium.

  5. Dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Dissociation_constant

    In chemistry, biochemistry, and pharmacology, a dissociation constant (K D) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions.

  6. Buffer solution - Wikipedia

    K w is the equilibrium constant for self-ionization of water, equal to 1.0 × 10 −14. Note that in solution H + exists as the hydronium ion H 3 O + , and further aquation of the hydronium ion has negligible effect on the dissociation equilibrium, except at very high acid concentration.

    In practice, it can be difficult to obtain statistically converged and accurate protonation free energies from titration curves if x is close to a value of 1 or 0. In this case, one can use various free energy calculation methods to obtain the protonation free energy [15] such as biased Metropolis MC, [24] free-energy perturbation, [25] [26 ...
