2. Imagine you have 3 different crystals and 3 agar gel plates (Agar is a gel used in microbiology
preparations). The crystals and their molecular weight is given below. If you place same amount of solution into a hole made in your agar gel plate and wait an hour the crystals will diffuse (see figure
1).
a. Methylene blue (molecular weight (MW) is 319.85 g/mol);
b. Potassium permanganate (MW is 158.03 g/mol);
c. Nigrosin (MW is453.5 g/mol)
Explain possible explanations for the differences noted among the diffusion rates of the three chemicals.
