Preface
Water is an important molecule. Seventy-one percent of the Earth’s
surface is covered by liquid water. it is the most abundant niolecule, and it
is a good solvent for polar and ionic substances. Samuel Taylor
Coleridge’s Ancient Mariner knew this:
The lack of pure water for drinking purposes and the lack of water
sufficiently pure for irrigating the land are major challenges for the
human race.
This book offers no solutions to such severe problems. It consists of a
review of the anic chemistry of the elements in all their oxidation
states in an aqueous environment. Chapters 1 and 2 deal with the
properties of liquid water and the hydration of ions. Acids and bases,
hydrolysis and solubility are the main topics of Chapter 3. Chapters 4 and
5 deal with aspects of ionic form and stability in aqueous conditions.
Chapters 6 (s- and p-block), 7 (d-block) and 8 (f-block) represent a survey
of the aqueous chemistry of the elements of the Periodic Table. The
chapters from 4 to 8 could forin a separate course in the study of the
periodicity of the chemistry of the elements in aqueous solution, chapters
4 and 5 giving the necessary thermodynamic background. A inore
extensive course, or possibly a second course, would include the very
detailed treatment of enthalpies and entropies of hydration of ions, acids
and bases, hydrolysis and solubility.
There are many tables of data in the text and the author has spent
much time in attempting to ensure maximum consistency with the various
available sources.
I thank Martyn Berry for reading the manuscript and for his many
suggestions that led to improvements in the text.
