When experimenting on a potatoes with sugar and salt and water should you peel off the potatoes skin?

Peeling the skin off potatoes before experimenting with sugar, salt, and water is not necessary, as the skin can affect the osmosis process. However, leaving the skin on may result in different absorption rates and texture changes compared to peeled potatoes. If your experiment aims to study the effects of solutes on the potato's flesh, peeling may provide clearer results. Ultimately, the decision depends on the specific goals of your experiment.
