Diffusion and Osmosis
Diffusion: Molecules travel from high
concentration to low concentration.
Osmosis: Put the solution in a
semi-permeable “cell” and dump the cell into water. If there are more water
molecules in the cell, water molecules go from the cell to the water until
equilibrium is reached. Vice versa.
Hypertonic: A solution that contains more
solvent than solute.
Hypotonic: A solution that contains more
solute than solvent.
Isotonic: A solution in which the solute
and solvent are equally distributed.
Water potential: affected mainly by two
factors—pressure and the amount of solute. Water always travels from high
potential to low potential.
In Part 2 and Part 4 of the experiment, we
proved the ranking of the molarity of the solutions through their percentage of
mass change. And there is sugar in different kinds of athletic drinks.
