Question 1.Which colour pigment was the smallest and most soluble in the experiment shown above?

To determine which color pigment was the smallest and most soluble, you would typically look at the results of the chromatography experiment or the solubility tests shown in the provided image. Since I don't have access to the image, I can't provide a specific answer.

However, generally speaking, smaller pigments tend to travel further up a chromatography paper and show higher solubility. You would need to compare the distances traveled by each pigment or their solubility characteristics documented in your experiment.

If you can provide more details or the results from your experiment, I would be happy to help you analyze them!
