HYDROPHILIC
The opposite of hydrophobic is hydrophilic,
which come from Ancient Greek root words for
“water” and “loving.” A hydrophilic substance is
attracted to water and tends to dissolve in water.
What would be some examples of hydrophilic
substances?
From Experiment 5, it
may seem that there
is a “repulsive force”
separating the oil and
water. However, it is just
the absence of attraction
that causes the two liquids
to separate.
Understanding how
polar and nonpolar
molecules interact is
also an important part
of creating cosmetics.
For example, it is
important that the oil
and water in creams
and lotions do not
separate when they sit
on the shelf.
The hydrophobic
effect
The tendency of a nonpolar
substance to separate out of a polar
substance, which you observed
in Experiment 5, is known as the
hydrophobic effect.
This phenomena is critical for the
function of cells, and thus life itself!

HYDROPHOBIC

Ancient Greek roots for “water” and “fear.”
Hydrophobicity is the physical property of a
