Answer 3

This is what I have so far.
Paper chromatograohy is used to help seperate mixtures that are in dissolved substances. So, by putting four differetn colored dyes on a piece of coffee filter and putting it in the NaCl solution you can see the mixtures break apart.

Answer 4

Answer 5

why they break apart?
how is the polarity of the components and how far in the chromatogram they went?
what is the stationary phase and the mobile phase?
How did you calculate the Rf?
What the Rf means?
Chromatography paper, and paper in general, is highly hydrophilic. Paper is made from a natural polymer called cellulose, which is a long chain of glucose molecules. Glucose is a cyclic structure with a number of —OH groups around the ring.
a. Predict and explain the types of intermolecular forces that would occur between paper and water. How do these interactions account for the hydrophilic nature of paper?
b. Explain the types of intermolecular interactions that would occur between the food dye Red , Blue and
Yellow and the paper
