Write the chemical equation and the Ka expression for the acid dissociation for the aqueous solution: HCOOH Acid Dissociation Constant: Magnitudes of ionization reaction equilibrium constants are used in the determination of the strengths of acids and bases. Th...
Henderson-Hasselbalch equation a formula for calculating the pH of a buffer solution such as blood plasma, pH = pKa + log [BA/HA]; [HA] is the concentration of a free weak acid; [BA] the concentration of the ionized form of this acid; pKa the acid dissociation constant, a measure of...
Dissociation constantsError calculationActivity coefficient of protonEquivalence volumesIt is shown that acid–base titration can be treated, in general, as an additive property. This is based on the fact that the average charge on the undissociated and dissociated solute species at equilibrium is an...

The meaning of HENDERSON-HASSELBALCH EQUATION is an equation that equates the pH of a buffered solution (as the blood) to the sum of the cologarithm (p) of the dissociation constant (K) of the acid in the buffer and the logarithm of the ratio of the conc
The Henderson-Hasselbalch equation solves for the pH of a solution using pKa, which is the negative log of the acid dissociation constant. This value is an equilibrium constant for the reaction of HA⇌A−+H+, which is a measure of how strong an acid HA is. If Ka is large and pKa...
The Henderson Hasselbalch equation can be developed by taking an example of the dissociation of a weak acid, HA. The dissociation is,Ha+H2O⇆A−+H2O+Ha+H2O⇆A−+H2O+Then the dissociation constant Ka can be calculated as,ka=[a−][H3O+]/[HA]ka=[a−][H3O+]/[HA]...
TheHenderson Hasselbalch equationisan approximate equation that shows the relationship between thepHor pOH of asolutionand the pKaor pKband the ratio of theconcentrationsof the dissociated chemical species. In order to use the equation, the acid dissociation constant must be known. ...
the formula for calculating the pH of a buffer solution, which states that: where pK is the dissociation constant of an acid. The variable term is really a ratio of concentration values and can be taken as being proportional to the amount of acid and base added in the buffer. For exampl...
