Quantitative Chemical Analysis
One of our most pressing problems is the need for sources of energy to replace oil.
The chart at the right shows that world production of oil per capita has probably
already peaked. Oil will play a decreasing role as an energy source and should be
more valuable as a raw material than as a fuel. There is also strong pressure to minimize
the burning of fuels that produce carbon dioxide, which could be altering
Earth’s climate.
It is my hope that some of you reading this book will become scientists, engineers,
and enlightened policy makers who will find efficient, sustainable ways to harness
energy from sunlight, wind, waves, biomass, and nuclear fission and fusion.
Nuclear fission is far less polluting than burning oil, but difficult problems of waste
containment are unsolved. Much coal remains, but coal creates carbon dioxide and
more air pollution than any major energy source. There is a public misconception
that hydrogen is a source of energy. Hydrogen requires energy to make and is only a
means of storing energy. There are also serious questions about whether ethanol provides
more energy than is required for its production. More efficient use of energy
will play a major role in reducing demand. No source of energy is sufficient if our
population continues to grow.
My goals are to provide a sound physical understanding of the principles of analytical chemistry
and to show how these principles are applied in chemistry and related disciplines—
especially in life sciences and environmental science. I have attempted to present the subject
in a rigorous, readable, and interesting manner that will appeal to students whether or not
their primary interest is chemistry. I intend the material to be lucid enough for nonchemistry majors yet to contain the depth required by advanced undergraduates. This book grew out of an introductory analytical chemistry course that I taught mainly for nonmajors at the University of California at Davis and from a course for third-year chemistry students at Franklin and Marshall College in Lancaster, Pennsylvania.
