Answer:
According to Le-chatelier principle, equilibrium will shift towards left to minimize concentration of
and keep same equilibrium constant
Explanation:
In this buffer following equilibrium exists -
![NH_{3}(aq.)+H_{2}O(l)\rightleftharpoons NH_{4}^{+}(aq.)+OH^{-}(aq.)](https://tex.z-dn.net/?f=NH_%7B3%7D%28aq.%29%2BH_%7B2%7DO%28l%29%5Crightleftharpoons%20NH_%7B4%7D%5E%7B%2B%7D%28aq.%29%2BOH%5E%7B-%7D%28aq.%29)
So,
is involved in the above equilibrium.
When a strong base is added to this buffer, then concentration of
increases. Hence, according to Le-chatelier principle, above equilibrium will shift towards left to minimize concentration of
and keep same equilibrium constant.
Therefore excess amount of
combines with
to produce ammonia and water. So, effect of addition of strong base on pH of buffer gets minimized.
