One method that some people use to remember the names of these
four acids involves paying attention to the number of oxygen atoms in the
formula. The acid that has four atoms of oxygen in its formula gets the
prefix “per-,” which is derived from the prefix “hyper-,” meaning “greater
than.” The acid with only one oxygen atom in its formula gets the prefix
“hypo-,” meaning “less than.”
Practice the rules for naming acids by answering the following review
questions.

Lesson 9-4: Theories of Acids and Bases
It may surprise you to find that, despite the reason that acids and bases
are found in so many of the materials around us, there are several different
theories defining what acids and bases are. The real difference between
the theories has to do with how broad or limited our definitions of acids
and bases should be. For example, should only compounds that ionize to
release hydroxide ions (OH
-
) be considered bases, or should other com-
pounds that neutralize acids without releasing hydroxide ions be included
in our definition? Examine the following theories.
