We would like to thank our teacher, Ms Tan Beng Chiak for demonstrating these 2 experiments to us :)

Flame Test and Chromatography

The numbers on the cheque were cut out to perform chromatography

The ink was dissolved in ethanol. After that, the ethanol was dripped onto a piece of chrmatography paper using a microtube. Dip the chromatography paper in distilled water so as to physically separate the different components of ink.Draw a line at where the distilled water travels to on the chromatography paper.

Chromatography

The picture on the left shows how the ink is dissolved in ethanol and the other picture shows the physical separation of the different components on the ink.

This is a picture of Flame Test. Note that the colour of flame will be different with different metals. This orange red colour shows that it is burnt from calcium.

The left picture shows a greenish flame that is burnt from copper. The right photo shows a bright orange colour that is probably burnt from sodium.
