Malachite green (green, molecular weight = 929 amu)
Potassium permanganate (Purple; molecular weight 158 amu)
After 1 hour
After studying the picture above and this video https://www.youtube.com/watch?v=zvzeebPrMpKGZs, what conclusion can you draw regarding the effect of size (molecular weight) on the rate of diffusion?
Actually, conclusions cannot be drawn because no diffusion was observed.
The larger the substance, the faster the diffusion rate.
Molecular size does not affect the rate of diffusion.
The smaller the substance, the faster the diffusion rate.
