In my lab I found that potatoes soaked in lactose had a positive growth in mass, while the other solutions (sucrose, glucose, fructose and maltose) had a negative growth. Any suggestions?
Mol mass was calculated correctly with the same amount of water, all variables were though of... Cannot find an explanation

Hi!

Were you able to replicate your results? For example, did you have any replicates where you noticed this in all test subjects?

The reason I ask is that the more you test it with different pieces of potatoes, and the more consistent your results are, the easier it'll be to make a conclusion.

The only inference that I can make is that lactose being a disaccharide is too large to fit pores (proteins) found within the cell membrane of the potato's cells.

Good luck, get back to me
