Soluble and insoluble materials - Experiment -

29.  Substances that dissolve in
water are crystalline and
have a grainy texture

32.  Substances that do not
dissolve in water have a
powdery and dry texture
since they are not crystalline.

35.  Substances dissolve each
other if they LIKE each
other. We call them
SOLUBLE.
 “likes dissolve likes”
Ex. Polar to Polar
Positive to Positive
Negative to Negative

36.  Solids that do not dissolve in
water are called INSOLUBLE
materials. They do not like each
other.
Ex. Positive to negative
Polar to Non-Polar
 Some insoluble solids that spread
throughout the liquid making it
appear cloud are called
SUSPENSION.

37. Do all solids dissolve
in liquids? What do
you call the solids that
do not dissolve in
liquids?
What about those that
solids that spread
throughout the liquids
making it cloudy?

38. Why do medicine
suspensions
need to be
shaken before
they can be
taken?

39. Because it is called a
"suspension" drug, this
means the drug is in a
suspension vehicle and it
will settle when left alone.
So it has to be
shaken to disperse the
drug through the syrup. If
you took it without
shaking, you just got the
plain syrup and most of the
medicine was probably
settled at the bottom of
your container.
