Worked Solution & Example Answer:The chromatography paper, with the spot of mixture on it, was placed in a beaker with the bottom of the paper in water - Edexcel - GCSE Chemistry - Question 2 - 2016 - Paper 1
Step 1
Complete the diagram showing the position of the chromatography paper with the spot of mixture at the start of the experiment
Answer
In the diagram, draw the chromatography paper vertically positioned in the beaker, ensuring that the bottom edge is submerged in the water while the spot of mixture is above the water level to indicate that it has not yet started to travel. Label the position clearly for clarity.
Step 2
Figure 3 - Indicate results
Answer
In Figure 3, a labeled diagram should show:
- The solvent front marked at the highest point reached by the solvent.
- The blue spot and the red spot, indicating the positions of different components of the mixture after chromatography.
- Distances marked in centimeters (X cm) to show how far each spot has traveled relative to the solvent front.
