which simplifies to pH = pKa + log (moles CH3COO–)o (moles CH3COOH)o and when we add a strong base the buffer capacity is defined by the equation (moles weak base)o + moles OH– (moles weak acid)o − moles OH– = 10 Example 3 = 7 20 + log 0 1435 0 1837 = 7 09
[PDF] Buffer Preparation and Capacity
The buffering capacity of a solution is determined using the Henderson-Hasselbalch Equation, and the closer the ratio of acid to conjugate base is to one the higher buffering capacity A buffer also can consist of a weak base and its conjugate acid as well
[PDF] pH buffers Buffer capacity and buffering range
Based on the Henderson-Hasselbalch equation, it can be seen that the pH of the buffer solution is equal to the pKa value of the acid, when the ratio of
