Which kind of tonicity is this

[From: ] [author: ] [Date: 11-05-25] [Hit: ]
There is an apparatus consisting of two tubes with a semi-permeable membrane between the two sides. The membrane is permeable by glucose and water but not sucrose. In the right tube, there are 2M sucrose and 1M glucose. In the left tube, there are 2M Glucose and 1M sucrose. Which side as more tonicity?

I know there is hypertonicity, hypotonicity, and isotonicity but I don't understand which one fits this situation. Any help is greatly appreciated.

Like osmotic pressure, tonicity is influenced only by solutes that cannot cross the membrane, as only these exert an osmotic pressure. Solutes able to freely cross the membrane do not affect tonicity because they will always be in equal concentrations on both sides of the membrane.

For myself, being a more visual person, I use videos. i.e."tonicity animation"
