SOLUTIONS
• We are learning to
FOLLOW A METHOD AND
ANALYSE DATA FROM FIRST
HAND INVESTIGATIONS
• At the end of this session I
will be able to
GIVE EXAMPLES TO
IDENTIFY THAT A SOLUTION
IS MADE UP OF A SOLVENT
AND SOLUTE
Soluble or insoluble
• Substances that dissolve in a solvent
are called SOLUBLE.
• Substances that do not dissolve in a
solvent are called INSOLUBLE.
Solution = solute + solvent
SOLVENT
SOLUTE
The substance into which
something will dissolve
(disappear)
• What dissolves into the
solvent

Water is a UNIVERSAL SOLVENT
This means that most things will dissolve in water.
However, there are other solvents and in todays practical we are
going to investigate these.
• This means it can dissolve
more substances than any
other liquid.
• It can actually dissolve
thousands of substances and
this is why it is so important
to all living things on Earth.
