Nitric acid, with a pK value of ca. -1.7, behaves as a strong acid in aqueous solutions with a pH greater than 1. At lower pH values it behaves as a weak acid. pK a values for strong acids have been estimated by theoretical means. For example, the pK a value of aqueous HCl has been estimated as −9.3. … See more In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted $${\displaystyle K_{a}}$$) is a quantitative measure of the strength of an acid in solution. It is the See more According to Arrhenius's original molecular definition, an acid is a substance that dissociates in aqueous solution, releasing the hydrogen ion H … See more An acid is classified as "strong" when the concentration of its undissociated species is too low to be measured. Any aqueous acid with a pKa value of less than 0 is almost completely … See more A polyprotic acid is a compound which may lose more than 1 proton. Stepwise dissociation constants are each defined for the loss of a single … See more The acid dissociation constant for an acid is a direct consequence of the underlying thermodynamics of the dissociation reaction; the pKa value is directly proportional to the standard Gibbs free energy change for the reaction. The value of the pKa changes … See more An acid dissociation constant is a particular example of an equilibrium constant. The dissociation of a monoprotic acid, HA, in dilute solution can be written as See more After rearranging the expression defining Ka, and putting pH = −log10[H ], one obtains This is the See more WebThe rationale for PK/PD-modelling is to link pharmacokinetics and pharmacodynamics in order to establish and evaluate dose-concentration-response relationships and subsequently describe and predict the effect-time courses resulting from a drug dose. Under pharmacokinetic steady-state conditions, concentration-effect relationships can be ...
