Chapter 19, Problem 19.123P

Interpretation Introduction

Interpretation:

A curve of $\left[H_3{O}^{+}\right]$ vs. mL of added $NaOH$ has to be plotted and whether there is advantages or disadvantages to viewing the result in this form has to be decided.

Concept Introduction:

For the titration of a strong acid with a strong base, the $pH$ before the equivalence point depends on the excess concentration of acid and the $pH$ after the equivalence point depends on the excess concentration of base.  At the equivalence point, there is not an excess of either acid or base so the pH is 7.0.  The equivalence point occurs when total volume of base has been added. 

$pH=-\log \left[H_3{O}^{+}\right]$

$pH=-\log \left[O{H}^{-}\right]$

$pH+pOH=14$
