Unen. QUESTION 17 0.5 points In this exercise, potato cylinders that were cut to 5.0 cm in length were exposed to concentrations of salt from 0% to 15% for a prolonged period of time (a few hours or days). By examining the lengths of the cylinders through time, you can determine whether water moved in or out of the potato cells and describe the overall effect of these solutions on the appearance and texture of the potato cylinders. Table 8-3 Lengths of potato cylinders in various salt concentrations Concentration of Length of Potato Length of Potato Length of Potato Average Length (cm Salt (%) Cylinder (cm) Cylinder (cm) Cylinder (cm) 096 5.1 0.9% 1096 8.

Answer 1

Answer. The average length of potato cylinder decreased as the concentration of salt in the external solution increased.

See in water its 5.1cm it is maximum,

And, at 1.8% NaCl it is the least with 4.7 cm

With increased NaCl concentration, hypertonicity is increasing, that is causing hindrance of water going into the potato cell, thus, affecting its length adversely.
