Chapter 17, Problem 160DIA

Interpretation Introduction

Interpretation:

A chemical equation showing the reaction between citric acid and hydroxide ion is to be written.

The citrate salts that would be used to make a buffer with a pH range of 5.5-6.5 is to be listed.

The reaction of a buffer system (from part b) with oncoming acid and incoming bas is to be shown.

The buffer region involving the salts chosen in b part is to be indicated on the graph that represents a titration curve for citric acid with a strong base.

In order to prepare a buffer with pH=6.0, the proper ratio of the concentrations of the two citrate salts (from part b) is to be listed. Along with this, the minimum concentration for each of the two buffer components is to be calculated if the buffer neutralizes at least 0.001 M acetic acid.
