Chapter 16, Problem 16.45QE

Interpretation Introduction

Interpretation:

The minimum concentrations of formic acid and sodium formate that are needed to prepare $500mL$ of a $pH3.80$ buffer whose $pH$ will not change by more than $0.10$ if $1.00mLof0.100M$ strong acid or strong base is added have to be calculated.

Concept Introduction:

The addition of a strong acid to an acidic buffer solution decreases the $pH$ of the buffer by not more than $\mathrm{0.10.}$  The addition of a strong base to an acidic buffer solution increases the $pH$ of the buffer by not more than $\mathrm{0.10.}$
