Question

In the thistle funnel experiment, the energy necessary for the solution to stop osmosis is provided by

• A. Hydrostatic pressure developed in the contents of beaker
• B. Wall of the beaker which exert pressure on water
• C. Hydrostatic pressure developed in the solution due to presence of solute
• D. Hydrostatic pressure developed in the solution due to rise in the level of solution

Answer 1

The correct option is D

Hydrostatic pressure developed in the solution due to rise in the level of solution

The hydrostatic pressure developed in the thistle funnel is equal to the amount of energy lost by the sucrose solution due to solute. Due to this hydrostatic pressure, the system reaches equilibrium and osmosis stops.
