Experiment with potato and salt water

When the solution is hypersonic, the potato Will decrease in size making the potato hypotonic. Osmosis is really interesting, that is why chose to write this report about it. Materials and Methods We first cut out six cores out of a potato. We trimmed them all to the same length using a razor. After we had cut them to the same size we weighed them using a scale. The weight ranged from . Egg to . Egg. As the potatoes were being trimmed and weighed, I prepared five various solutions of salt water.

When the potatoes and water both prepared, we put the potatoes in the salt water and allowed them to soak for 45 minutes. After the time expired we extracted the cores from the water. Once again we measured the length and weight. Results In first three test tubes, the potato core became shorter and avgas lighter than the original (see attached table and graphs). The length changed from mm to MIM and the weight changed from .

Egg to . Egg. In test tube four, the potato core remained the same length Of 28 mm, but was heavier than the original by . Egg (see attached table and graphs). In test tubes five and six, the potato core increased in size by MIM and norm and is heavier by . Egg to . Egg than the original (see attached table and graphs). Discussion My hypothesis was that the potato core will increase in size when it is hypersonic to the salt solution. I also predicted the potato will decrease in size when it is hypotonic.

My results showed that when the solution contained a higher percentage salt than the potato, the potato got smaller, displayed in the first three test tubes.

Test tube four displayed that when the solution is similar to the Toto not much change takes place in the core. The potato core increased in size and weight in test tubes five and six, displaying that when the potato contained a higher percentage of salt would increase in size and weight.
