Question

24. Two beakers A and B are taken Beaker A is filled with normal water and bealter B is fillet with a
concentrated solution of sugar. A few raisins are put in both the beakers
(a) What will happen to the raisins put in both the beakers? What will be the right observation
(b) What if we keep iron nails instead of raisins in water.​

Answer 1

Answer:

Raisins in the beaker A will swell as solution surrounding them is hypotonic in nature. Hypotonic solution contains lesser solute concentration. In such case, endosmosis will occur in which inward movement of the water molecules from the lower solute concentration to higher solute concentration through raisin covering.

Raisins in the beaker B will shrink as solution surrounding them is hypertonic in nature. Hypertonic solution contains higher solute concentration. In such case, exosmosis will occur in which outward movement of the water molecules from the lower solute concentration to higher solute concentration through raisin covering.
