What fraction of an acetic acid/sodium acetate buffer (pka of acetic acid= 4.76) is present in the acidic form at pH= 5.20?
The pH value of a buffer solution can be calculated by the following eqation:
pH=pKa+p([A]/[B]) in which [A] is the concentration the conjuated acid (here is the acetic acid), [B] is the concentration of the base ( sodium …
The fraction of an acetic acid/sodium acetate buffer is examined. The pKa of acetic acid is determined.
