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 drawn 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 than that of solution A and lower than 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
Correct answer: (2) sugar concentration of raisins is higher than that of solution A and lower than that of solution B.
Explanation:
In the first case, the sugar concentration of raisins was less as compared to the solution in the beaker. As a result, water moves into the raisins causing them to swell.
