Introduction Hypothesis Experimental Items Experimental Process Experimental Results Analysis 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 paperwater table salt a ruler 5 toothpicks an empty 1litre bottle

1. Cut out a rectangular piece of filter paper.

2. Dissolve each M&M’s chocolate in water to obtain colour solution

3. Use a toothpick, obtain some dye solution, and then place it onto the filter paper

4. Repeat Step 3 several times to make the dye solution concentrated.

5. Dissolve 1/8 teaspoon of salt into 1 litre of water to form a 1% salt solution.

6. 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.
