What Are Hypertonic, Hypotonic, and Isotonic Solutions in Dialysis Experiments?

[DespicableMe]

Homework Statement

Purpose: To use dialysis tubing and two different solutions, water and a concentrated starch solution, to demonstrate hypertonic, hypotonic and isotonic solutions.

I'm confused as to which situation is hyper or hypotonic:

The Attempt at a Solution

If the water is placed INSIDE the tube and the starch solution is in the beaker, that would be a HYPERTONIC situation because water concentration inside is higher?

If the water is placed OUTSIDE the tube and starch is placed INSIDE the tube, that would be a HYPOTONIC situation because water concentration inside is lower (than in the beaker)?

We only talk about hypo- and hypertonic situations in terms of the WATER solution because it is the only solution out of the two used that can diffuse in and out of the dialysis tube, right?

There was also one section where it asked us to repeat the HYPERTONIC situation at a different temperature to look for the RATE of transport.

We did not have enough time to complete this part so I was wondering if there is any insight on that.

Thanks : )

Hypertonic = more solute = less water

Particles move faster at higher temperatures, and diffusion is the movement of particles...
