Answer:
Here's what I get.
Explanation:
(a) The buffer equilibrium
The equation for the buffer equilibrium is
[tex]\rm CH_{3}COOH(aq) + H$_{2}$O(l) $\, \rightleftharpoons \,$ CH$_{3}$COO$^{-}$(aq) + H$_{3}$O$^{+}$(aq)[/tex]
(b) Addition of acid
If you add a strong acid like HNO₃, you are increasing the concentration of hydronium ion.
Per Le Châtelier's Principle, the system will respond in such a way as to decrease the concentration of hydronium ion.
The position of equilibrium will shift to the left.
(c) Addition of base.
If you add a strong base like KOH, The hydroxide ions will react with the hydronium ions to form water.
The concentration of hydronium ions will decrease.
Per Le Châtelier's Principle, the system will respond in such a way as to increase the concentration of hydronium ions.
The position of equilibrium will shift to the right.
