Effects of Salt Concentration on Osmosis in Potato Cells

Very Hard Data Representation Interpreting Experimental Data

In a controlled experiment, researchers investigated the effect of different concentrations of salt (NaCl) on the rate of osmosis in potato cells. They prepared potato slices and immersed them in solutions with salt concentrations of 0%, 1%, 2%, and 3%. After a period of 24 hours, they measured the change in mass of the potato slices. The data collected is as follows:

0% NaCl: 10.5g (initial) → 11.1g (final)
1% NaCl: 10.5g (initial) → 10.7g (final)
2% NaCl: 10.5g (initial) → 10.3g (final)
3% NaCl: 10.5g (initial) → 9.8g (final)

Based on the data obtained, which of the following conclusions is best supported regarding the impact of salt concentration on osmosis in potato cells?

Higher salt concentrations lead to an increase in mass of potato slices due to osmosis.

Potato cells gain mass in salt solutions less than 2% due to osmotic pressure.

There is no effect of salt concentration on the rate of osmosis in potato cells.

Higher salt concentrations cause potato cells to lose mass due to water moving out.
