  • May 19, 2015 · The second experiment we did involving diffusion and osmosis was the Agar Lab. Agar is a type of gelatin that contains a chemical known as Phenothayline. Phenothayline is a white or yellowish white crystalline compound that is used in analysis as an indicator because its solution is brilliant red in alkalies and is decolorized by acids.

The most concentrated solutions would be Solution A (purple), Solution B (red), and Solution D (yellow). This grouping can be deduced by considering osmosis- if the sucrose solution in the beaker is higher than the sucrose concentration of the cell (hypertonic), water will leave the cell in an attempt to reach an isotonic state.
ap biology diffusion and osmosis lab hypothesis, A number of factors can affect the rate of diffusion, including temperature, molecular weight, concentration gradient, electrical charge, and distance. Water can also move by the same mechanism. This diffusion of water is called osmosis.

In our lab, we modeled diffusion and osmosis with an interesting scenario. It is important for a solution to have salts in it so the water and solute can be equal to create an isotonic environment. However, if there was nothing, it would either be a hypotonic causing the cell to expand and burst or it would be hypertonic causing the cell to shrink.
