1)
a. The dye bands looked about the same length as the reference bands, maybe a little bit smaller but not too much.
b. The dyes were the same colors as the reference band, but slightly different shades or hues.
c. The blue and yellow from the candies stacked up to form one band with the yellow on top and the blue below.
d. All of the dyes moved in the "right" direction.
These dyes might be slight variations in the specific candy used. Also, it could depend on how much of the dye you squirted into the gel, producing a bolder or lighter color.
2) Fast green FCF, and Citrus red 2 have similar structures to the dyes used in this lab, so they might migrate similarly.
3) Dog food manufacturers might put artificial food colors in dog food to appeal to the humans who are buying them. They don't appeal to the dogs because the dogs don't see the colors.
4) I think I eat mostly food that doesn't have dye in it, especially since I'm vegetarian. But food that I eat occasionally that have dyes in them could be chips, gummies, and cake.
5) length and speed control the distance that the colored dye solutions migrate.
6) and electrical current helps move the dyes through the gel.
7) Smaller molecules get more excited and move faster and farther. Larger molecules get less excited and move slower and less far.
8) They would separate in the following order from closest to farthest: 600, 1000, 2000, 5000.
