I need three limitations, and ways to overcome them, the one I already have is the the strip size may vary, and you could use a set size cork borer to ensure they're the same size.
Could someone help me as to what the other two are? As an experiment it doesn't have many, and I'm struggling to see them thanks
Some strips might have 'skins.' These would act as a barrier to reduce the rate of osmosis. You could replace these with strips without skins.
You might blot them before putting them in the solutions. Inconsistent blotting might lead to some strips being left with more excess water than others. In order to overcome this you could blot them gently and consistently in circular motions.
Control the volume of solution used for each strip.
Anomalous results... you could do repeats and calculate the mean.
when blotting the chips after osmosis, theres a risk of forcing water out of the cells, affecting the change in mass
I forgot the rest lol, need to look over my notes.
