The Effect of Varying Molecular Weights on the Rate of Diffusion of Substances August 22‚2012 ABSTRACT The effect of molecular weight on the rate of diffusion was verified by the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup‚ two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed on both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused

In this laboratory experiment is stating that organic lipids have the ability to dissolve lipids membranes‚ and in this exercise acetone would be the main source to be used to have the reaction of dissolving the lipids inside the tubes. This exercise was to be able to observe how the chemicals reacted in rare temperatures such in heat and in cold weather‚ also this type of changes can create a new color either making the color lighter or darker. The reaction of a light color would be that it did
