Question

Fresh grapes shrink when placed in:

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

Concentrated salt solution

Fresh grapes shrink when placed in a concentrated salt solution as the movement of water (osmosis) takes place from higher water concentration to lower water concentration. The salt solution is hypertonic with respect to the pulp of the grape.
