 Conlusion
 An
experiment was done on M&M’s
chocolate candies as they are made up of
different colours namely: red, blue,
green, yellow, brown and orange
 Aim of experiment was to find out the
different types of colours involved
through the use of chromatography.
 M&M
uses the same type of food
colouring for each of the different
candies.
The items used:
 M&M (one of each colour)
 filter paper
 water
 table salt
 a ruler
 5 toothpicks
 an empty 1litre bottle

Cut out a rectangular piece of filter
paper.
Dissolve each M&M’s chocolate in water
to obtain colour solution
Use a toothpick, obtain some dye
solution, and then place it onto the filter
paper
Repeat Step 3 several times to make the
dye solution concentrated.

6.
Dissolve 1/8 teaspoon of salt into 1 litre
of water to form a 1% salt solution.
Submerge the filter paper into the salt
solution and see
It was observed that some colours such as
orange did not break down into colours
such as red and yellow whereas green
separates into yellow and blue.
 Thus, we
can conclude that M&M candies
uses different types of food colouring on
each of the different colour of the
candies.
 And
hence, the hypothesis was proven
wrong.
