Some students investigated osmosis in raw potato sticks.
The students measured the mass of three potato sticks using an electronic balance. The students left each potato stick in one of the three different liquids for 5 hours:
i. distilled water
ii. dilute sodium chloride solution i
iii. concentrated sodium chloride solution
After the experiment the students noticed that the potato stick with the lowest mass was soft and floppy. Explain why the potato stick had become soft and floppy.
