Question
Define Buffer solution. Write the Henderson Hasselbalch equation for acidic buffer.
✓
Answer
Buffer solution:
Buffer solution is defined as a solution which resists drastic changes in pH when a small amount of strong acid or strong base or water is added to it.
Henderson Hasselbalch equation for acidic buffer:
$p H=p K_a+\log _{10} \frac{[\text { salt }]}{[\text { acid }]}$
Where, $p K_\alpha=-\log _{10} K_a$ and $K_a$ is the dissociation constant of the acid.
