Question

Fresh grapes shall shrink when they are placed in

• A. Hot water
• B. Cold water
• C. Starch water
• D. Concentrated salt solution

Answer 1

The correct option is D Concentrated salt solution

Fresh grapes shrinks when they are placed in a concentrated salt solution as the salt solution is hypertonic as compared to the sugar and water inside the grapes. Being a hypertonic solution, it has lesser concentration of solvent molecules than the fluid inside the cell. So the solvent molecules are forced outside the cell from the region of higher concentration to the lower concentration by the process of exosmosis. The cell turns flaccid.

So, the correct answer is option D.
