Answer : The pH of a 0.1 M phosphate buffer is, 6.86
Explanation : Given,
![pK_a=6.86](https://tex.z-dn.net/?f=pK_a%3D6.86)
Concentration of acid = 0.1 M
Concentration of conjugate base (salt) = 0.1 M
Now we have to calculate the pH of buffer.
Using Henderson Hesselbach equation :
![pH=pK_a+\log \frac{[Salt]}{[Acid]}](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%20%5Cfrac%7B%5BSalt%5D%7D%7B%5BAcid%5D%7D)
Now put all the given values in this expression, we get:
![pH=6.86+\log (\frac{0.1}{0.1})](https://tex.z-dn.net/?f=pH%3D6.86%2B%5Clog%20%28%5Cfrac%7B0.1%7D%7B0.1%7D%29)
![pH=6.86](https://tex.z-dn.net/?f=pH%3D6.86)
Therefore, the pH of a 0.1 M phosphate buffer is, 6.86
