Question

Grapes placed in three beakers $X,Y$ and $Z$ containing different type of solutions are shown in figures.
If beaker $X$ contains water, $Y$ and $Z$ contains:

• A. $Y$- hypotonic solution; $Z$- hypertonic solution
• B. $Y$- hypertonic solution; $Z$- hypotonic solution
• C. $Y$ and $Z$- isotonic solutions
• D. $Y$ and $Z$- hypotonic solutions

Answer 1

The correct option is A $Y$- hypotonic solution; $Z$- hypertonic solution

$Y=$ hypotonic solution as the size of grape is increasing because of the movement of solvent molecules from solution to the grape.

$Z=$ hypertonic solution as size of grape is reducing because of the movement of solvent molecules from grape to the solution.
