The pH of the buffer is 6.1236.
Explanation:
The strength of any acid solution can be obtained by determining their pH. Even the buffer solution strength of the weak acid can be determined using pH. As the dissociation constant is given, we can determine the pKa value as the negative log of dissociation constant value.
![pKa=-log[H] = - log [ 5.66 * 10^{-7}]\\ \\pka = 7 - log (5.66)=7-0.753=6.247\\\\pka = 6.247](https://tex.z-dn.net/?f=pKa%3D-log%5BH%5D%20%3D%20-%20log%20%5B%205.66%20%2A%2010%5E%7B-7%7D%5D%5C%5C%20%5C%5Cpka%20%3D%207%20-%20log%20%285.66%29%3D7-0.753%3D6.247%5C%5C%5C%5Cpka%20%3D%206.247)
The pH of the buffer can be known as
![pH = pK_{a} + log[\frac{[A-]}{[HA]}}]](https://tex.z-dn.net/?f=pH%20%3D%20pK_%7Ba%7D%20%2B%20log%5B%5Cfrac%7B%5BA-%5D%7D%7B%5BHA%5D%7D%7D%5D)
The concentration of ![[A^{-}] = Moles of [A]/Total volume = 0.608/2 = 0.304 M\\](https://tex.z-dn.net/?f=%5BA%5E%7B-%7D%5D%20%3D%20Moles%20of%20%5BA%5D%2FTotal%20volume%20%3D%200.608%2F2%20%3D%200.304%20M%5C%5C)
Similarly, the concentration of [HA] = ![\frac{Moles of HA}{Total volume} = \frac{0.809}{2} = 0.404](https://tex.z-dn.net/?f=%5Cfrac%7BMoles%20of%20HA%7D%7BTotal%20volume%7D%20%3D%20%5Cfrac%7B0.809%7D%7B2%7D%20%3D%200.404)
Then the pH of the buffer will be
pH = 6.247 + log [ 0.304/0.404]
![pH = 6.247 + log 0.304 - log 0.404=6.247-0.517+0.3936=6.1236](https://tex.z-dn.net/?f=pH%20%3D%206.247%20%2B%20log%200.304%20-%20log%200.404%3D6.247-0.517%2B0.3936%3D6.1236)
So, the pH of the buffer is 6.1236.
<span>Anthropology is a science which studies human study of both in terms of culture, behavior, diversity, and so forth. Anthropology is a term word comes from the Greek word anthropos and logos. Anthropos meaning human and logos means story or word.
The object of anthropology is human in society ethnicity, culture and temperament. The science of anthropology has the purpose to study the human being in society tribes, behaved and cultured to build community itself<span>.</span></span>
