Question

What types of molecules are in food dyes? (polar or nonpolar or both)?

Please explain. Thank you

Answer 1

why not google the structures of some of the dyes?

I'm sure there are both kinds

Answer 2

I am doing this experiment at school. I need to know the type of the molecules of the food?

Answer 3

Can you explain the experiment and the observations a bit more?

Answer 4

I actually have to go, i'll see this when i come back

Answer 5

Ok, this activity relates molecular motion to polarity and nonpolaritu of molecules. Milk consists of polar and nonpolar components. Detergents have polar and nonpolar regions to their molecules, therefore the constant attractions and repulsions between the different regions and types of molecules results in the motion (kinetic energy) that subsequently ensues.

Answer 6

Molecules of same and different polarities will repel and attract each other resulting in observable motions.

Answer 7

I just need to know what types of molecules are in food dyes? and what is the shape of the molecules in this activity?

Answer 8

i know the theory, i was talking more about the experimental observations. What did you see?

Answer 9

I saw the colours mixed up and move into different directions in the milk when the detergent was added. I assume the food colour was polar, but I already hand in the assignment to my teacher. Thank you for sharing your ideas. :)
