WHAT IS A in Henderson Hasselbalch equation?
The Henderson–Hasselbalch equation mathematically connects the measurable pH of a solution with the pKa (which is equal to -log Ka) of the acid. The equation is also useful for estimating the pH of a buffer solution and finding the equilibrium pH in an acid-base reaction.Click to see full answer. Keeping this in view, what is…

Keeping this in view, what is Henderson equation in chemistry?Updated August 10, 2019. The Henderson Hasselbalch equation is an approximate equation that shows the relationship between the pH or pOH of a solution and the pKa or pKb and the ratio of the concentrations of the dissociated chemical species.Likewise, what does pKa mean? Key Takeaways: pKa Definition The pKa value is one method used to indicate the strength of an acid. pKa is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger acid. That is, the lower value indicates the acid more fully dissociates in water. Herein, what is HA and A in chemistry? The HA is the acid – a proton and its conjugate base. H+ is the proton released when the acid dissociates in water (can also be written as H3O+, the hydroxonium ion) A- is the conjugate base (i.e. the bit left over after dissociation)Why do we use the Henderson Hasselbalch equation?The Henderson-Hasselbalch equation is useful for estimating the pH of a buffer solution and finding the equilibrium pH in an acid-base reaction. The equation can be used to determine the amount of acid and conjugate base needed to make a buffer solution of a certain pH.
