Chemistry Laboratory Experiment on Forming a Solution


Solutions play an important part in many processes that go on about us.  The ocean is a vast water solution containing different compounds extracted from the minerals of the earth.  A solution is a homogeneous mixture of molecules or atoms of two or more different substances.  A solution is made up of the solute and solvent.  A minimum of two substances are present.  A solute is any substances dissolved by the solvent.  While a solvent is a medium into which the other substances are dissolved or mixed.  Water is the most common solvent but not all materials is dissolved to water.

The nature of a solution may be better understood by picturing what is thought to happen when a lump of sugar is dissolved in water.  In this process sugar molecules break away from the lump of sugar and dispersed in water.

A solution is a mixture where only one phase is present.  Mixture is a combination of two or more substances in variable proportions.  The two kinds of mixtures are:

  • Homogeneous mixture
  • Heterogeneous mixture

In a homogeneous mixture, one phase is formed.  It means the component parts have the same properties all throughout.  It cannot be filtered and unable to scatter light.  In a heterogeneous mixture, definite surfaces can be detected.  It is also consists of two or more regions or phases that differ in properties.  Muddy water is an example of a heterogeneous mixture consisting of two phases, the small particles of clay and water.  The clay particles are not single single molecules but are composed of many particles clustered together.  The larger cluster can be seen with a microscope.  In time, they settle to the bottom, or they may be removed by filtration.

Solution can be:

  • Unsaturated solution.  Contains less than the maximum amount of solute that can be dissolved in a given amount of solvent at a given temperature.
  • Saturated solution.  Is one in which no more solute can be dissolve at a particular temperature.
  • Supersaturated solution.  An unstable condition in which there is more solute in solution than can normally exist at a given temperature.


a) To describe some properties of solution

b) To be able to prepare a solution


Table sugar, 3 test tubes, test tube rack, 50ml-beaker, graduated cylinder, straw, medicine dropper, nail polish, water, colored dye, oil 




1)  Pour about 30-ml of water into a 50 ml beaker and put a drop of colored dye.  Observe and record your observation.

2)  Get three clean test tubes and label them A, B, and C.

3)  Pour 10 ml of water in test tubes A, and B, pour 10 ml of acetone in test tube C.

4)  Add a pinch of sugar in test tubes A, use a straw to blow into the water in test tube B.  Add three drop of nail polish on test tube C and shake.

5)  Observe the solution formed in these three test tubes,  Identify the solute and the solvent used in each test tubes.

6)  Mix oil and water in a test tube.  Is a solution formed?  Why?



1)  What is a solution?

2)  List down four (4) solutions you use at home.

3)  A mixture of ice cubes and water is an example of homogeneous or heterogeneous mixture?  Why?

4)  Give examples each of the following types of solution:

  • gas in a liquid
  • liquid in a liquid
  • solid in a liquid
  • gas in a gas
