In chemistry and biochemistry, the Henderson-Hasselbalch equation :$\backslash ce\; pH\; =\; \backslash ce\; p\; K\_\backslash ce\; a\; +\; \backslash log\_\; 10\; \backslash left(\; \backslash frac\; [\backslash ce\; Base\; ]\; [\backslash ce\; Acid\; ]\; \backslash right)$ can be used to estimate the pH of a buffer solution. The numerical value of the acid dissociation constant, K_a, 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.
