Solution Preview

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 ...

Solution Summary

The fraction of an acetic acid/sodium acetate buffer is examined. The pKa of acetic acid is determined.
