Question

(b) P, Q, R and S are mixtures of food colourings. They are investigated using paper chromatography. Figure 3 shows the chromatogram at the end of the experiment. vilys pofather (i) Which mixture contains an insoluble food colouring? A mixture P C mixture R B D 30*6 mixture Q mixture S​

Answer 1

HOPE THIS HELPS

Step-by-step explanation:

Based on the given information, we can determine which mixture contains an insoluble food coloring by analyzing Figure 3, the chromatogram provided in the question.

Looking at the chromatogram, we observe that the food coloring bands for mixtures P, Q, R, and S are all different.

To identify the mixture containing an insoluble food coloring, we need to look for a band that does not move or does not separate into different colors during the experiment.

Upon careful observation of Figure 3, we can see that only mixture R has a single band that does not separate into different colors, indicating the presence of an insoluble food coloring.

Therefore, based on the chromatogram in Figure 3, mixture R contains an insoluble food coloring.
