Chapter 17, Problem 17.71QP

Interpretation Introduction

Interpretation:

Titration curve of weak acid–strong base indicating the volume of base used at the equivalence point and the half-equivalence point has to be drawn.  $p{K}_a$ of acid has to be determined.

Concept Introduction:

Equivalence point is a point in a titration where the amount of standard solution added is sufficient to neutralize the unknown solution completely.  At this point, the total number of moles of standard solution (titrant) is equal to the number of moles of unknown solution (analyte).

Henderson-Hasselbalch equation

  $pH=p{K}_a+\log \frac{\left[Conjugtedbase\right]}{\left[acid\right]}$
