Chapter 11.5, Problem 2TY

Interpretation Introduction

Interpretation:

The derivative in cell D7 of figure 11-6 has to be verified.

Concept introduction:

Titration curve is plotted for volume of the titrant versus $pH$ calculated.  Thus in titration calculations, the first derivative corresponds to $\Delta pH/\Delta V$ and the first derivative graph is plotted as volume of acid versus $\Delta pH/\Delta V$.  The second derivative corresponds to $\frac{\Delta \left(\Delta pH/\Delta V\right)}{\Delta V}$ and the second derivative graph is plotted as volume of acid versus $\frac{\Delta \left(\Delta pH/\Delta V\right)}{\Delta V}$.
