To calculate the molarities of CH3COOH and CH3COO^- in a buffer solution, you would use the Henderson-Hasselbalch equation:

pH = pKa + log([CH3COO^-]/[CH3COOH])

Solve for [CH3COO^-] and [CH3COOH] using the known values of pH and pKa, the dissociation constant of acetic acid.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
