A student places four identical potato cylinders into sugar solutions of different concentrations. Their masses before and after 1 hour are shown.
- Solution A: 0.1 mol/dm³, mass from 3.20 g to 3.50 g
- Solution B: 0.2 mol/dm³, mass from 3.18 g to 3.26 g
- Solution C: 0.4 mol/dm³, mass from 3.25 g to 3.10 g
- Solution D: 0.6 mol/dm³, mass from 3.22 g to 2.90 g
In which solution is the water potential closest to that of the potato cells?
- Solution A: 0.1 mol/dm³, mass from 3.20 g to 3.50 g
