This equation is used in clinical cases to determine the extent to which pH affects the blood.  
This equation is used in clinical cases to determine the extent to which pH affects the blood.  It requires knowledge of the concentrations of a weak acid and its conjugate base in solution, as well as the pKa, or dissociation factor, of the acid in question.  Applying mostly to systems with pHs between 6 and 8, this equation can be used to deduce the composition of a weak acid/weak base solution.  FTP, identify this chemistry equation used for the calculation of pH of a buffer solution named after its two developers.
