(Experiment 1: Diffusion through a liquid) Does the rate of diffusion correcspond with the molecular weight of the dye?

1 answer:

3 0

The answer to this question would be: False

The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.
