Henderson-Hasselbalch equation relates the pH with the dissociation constant of the acid. The pH of the buffer solution will be 3.90.
<h3>What is the Henderson-Hasselbalch equation?</h3>
The Henderson-Hasselbalch equation is used to calculate the pH or the concentration of the conjugate base and acid.
The Henderson-Hasselbalch equation can be given as,
pH = pKa + log [A⁻] ÷ [HA]
The dissociation reaction is given as,
HA⁺ + H2O ⇌ H3O⁺ + A⁻
NaA → Na⁺ + A⁻
For this first pKa is calculated as:
pKa = - log (1. 0 x 10⁻⁴)
Substituting the value of pKa in Henderson-Hasselbalch equation pH is determined as:
pH = - log (1. 0 x 10⁻⁴) + log [0.08] ÷ [0.1]
= 4 + (-0.0969)
= 3.90
Therefore, 3.90 is the pH of the solution.
