Question

1. Beaker A contains 100 ml of 5% salt solution and Beaker B contains 100 ml of 2% salt solution. Which solution is hypertonic? 2. Which beaker has the greater amount of solute, salt? 3. If the solution in beaker A was placed in bag made up of a selective permeable membrane and placed in beaker B, what would happen? Explain. 4. Is this process active or passive? Explain. 5. If a potato plug was placed in beaker B and the cells underwent plasmolysis, what does this tell you about the salt content in the cytoplasm of the potato cells.

Explanation / Answer

Part 1 - The 5% solution means the solution contain 5 part of solute and 95% part of solvent. Similarly the 2% solution contain 2 part of solute and 98 part of solvent. In case of tonicity we explain it in term of solute concentration . As the solution in beaker A has 5 % solution so hare the number of moles of solute is more as compared to beaker B . So the solution A is hypertonic as compared with solution B.
