Question

Henderson equation of acid and base​

Answer 1

Explanation:

The equilibrium between the weak acid and its conjugate base allows the solution to resist changes to pH when small amounts of strong acid or base are added. The buffer pH can be estimated using the Henderson-Hasselbalch equation, which is pH = pKa + log([A-]/[HA]).

Answer 2

Answer:

the Henderson–Hasselbalch equation

can be used to estimate the pH of a buffer solution. The numerical value of the acid dissociation constant, Ka, of the acid is known or assumed. The pH is calculated for given values of the concentrations of the acid, HA and of a salt, MA, of its conjugate base, A−; for example, the solution may contain acetic acid and sodium acetate.
