The purpose of this experiment is to explore the
hardness of the water on campus. Hard water has
been a problem for hundreds of years. One of the
earliest references to the hardness or softness of
water is in Hippocrates discourse on water quality
in Fifth century B.C. Hard water causes many
problems in both in the household and in the
industrial world. One of the largest problems with
hard water is that it tends to leave a residue when
it evaporates. Aside from being aesthetically
unpleasing to look at, the build up of hard water
residue can result in the clogging of valves, drains
and piping. This build up is merely the
accumulation of the minerals dissolved in natural
water and is commonly called scale. Other than
clogging plumbing, the build up of scale poses a
large problem in the industrial world. Many things
that are heated are often cooled by water running
through
piping. The build up of scale in these pipes
can greatly reduce the amount of heat the......
