Question

A student put five raisins each in two beakers A and B. Beaker A contained 50 mL of distilled water and beaker B has 50 mL of saturated sugar solution. After some time the student would observe that : (
a) raisins in beaker A were more swollen than those in beaker B.
(b) raisins in beaker B were more swollen than those in beaker A.
(c) raisins in both beakers A and B were equally swollen.
(d) raisins in beaker A did not swell up at all.

Solution

The answer is a) raisins in beaker A were more swollen than in beaker B.
Beaker A contains distilled water, the concentration of which is lesser than the cell saps of raisins. As a result of osmosis, water from lesser concentration moves towards the higher concentration of solution.

Q. A student soaked 5 g of raisins in beaker (A) containing 25 mL of ice-chilled water and another 5 g of raisins in beaker (B) containing 25 mL of tap water at room temperature. After one hour the student observed that:
(1) water absorbed by raisins in beaker (A) was more than that absorbed by raisins of beaker (B).
(2) water absorbed by raisins in beaker (B) was more than that absorbed by raisins of beaker (A).
(3) the amount of water absorbed by the raisins of both beakers (A) and (B) was equal.
(4) no water was absorbed by raisins in either of the beakers (A) and (B).

Q. Each of the three beakers A, B and C contained 50 mL of distilled water. A student placed five raisins in each beaker. The raisins for each beaker weighed the same. The beakers were kept at room temperature. The raisins were removed from beaker A after 10 minutes, from beaker B after 20 minutes and from beaker C after one hour. On calculating the percentage of water absorbed by the raisins, it was found that:
(1) maximum absorption of water by raisins was in beaker C
(2) maximum absorption of water by raisins was in beaker B
(3) minimum absorption of water by raisins was in beaker C
(4) absorption of water was equal in raisins of all the three beakers

Q. There are 3 beakers containing plain water- A,B and C. Salt is added to beaker B. Sugar is added to beaker C. A raisin is put in each of these beakers. In which of these beakers, size of raisin would be maximum?

Q. A Student dissolved 5 g of sugar in 100 mL of distilled water in beaker A. He dissolved 100 g of sugar in 100 mL of distilled water in beaker B. Then he dropped a few raisins of equal weight in each beaker. After two hours he found the raisins in A swollen and those in B shrunken. The inference drown is that:
(1) sugar concentration of raisins is lower than that of solution A and higher than that solution B.
(2) sugar concentration of raisins is higher that that of solution A and lower that that of solution B.
(3) in B the cell membrane of raisins was damaged resulting in bleaching.
(4) in A the permeability of water of the cell membrane of raisins was enhanced
