Materials Filter paper or paper towel Felt tip pens - not washable or permanent A container - glass, jar, or plate Water or alcohol as your solvent Experimental process: 1. Take a piece of chromatography paper (or filter paper/ paper towel). Draw a pencil line across it about 1 cm from one end. Using colored markers (pentel pen), place small spots of color on the center of the line. 2. Put water in the glass container to a depth of about 0.5 cm. Tape the chromatography paper in a pencil and hang it in the glass container so that it dips into the water but with spots of color above the water level. -Glass rc Pencil Strip of filter -Paper clip paper -Jar Strip of filter paper Spot of ink Line drawn by pencil -Water Spot of ink (a) (b) https //www topperlearning com/answerhow-will-you-separate-dyes-in-black-ink-using-chromatography-explain-if-with- the-holp-of-a-diagram/spxoq 7155 4. Allow the water to rise up the paper until it is almost to the top. 5. Remove the paper, mark where the water reached (solvent front), and hang it up to dry. 6. When dry, measure the distances moved by the spots and the solvent front. Draw your laboratory set-up: Write your observation here: Answer the following questions 1. Why should the line of the bottom of the paper be drawn on a pencil? 2. What would happen if the level of the solvent came above the level of the spots at the start? 3. Why should the solvent not be run off the top of the paper? 4. What color did you observe in the colored marker
