Title: Osmosis lab help - results are odd Post by: anneheey98 on Jan 4, 2017 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 Title: Re: Osmosis lab help - results are odd Post by: bio_man on Jan 4, 2017 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 |
