The diagram shows a set-up used to demonstrate osmosis. The 15% sugar solution is ........... the 30% sugar solution.

Understanding Osmosis

In the context of osmosis, we need to identify the concentration of solutions involved. Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Analyzing the Solutions

1. Identify the Solutions:

   • Solution A: 15% sugar solution
   • Solution B: 30% sugar solution

2. Concentration Comparison:

   • The 15% sugar solution has a lower concentration of solute compared to the 30% sugar solution.

Direction of Osmosis

Therefore, water will move from the 15% sugar solution (an area of lower solute concentration) to the 30% sugar solution (an area of higher solute concentration).

Final Answer

The 15% sugar solution is hypotonic relative to the 30% sugar solution, which is hypertonic. Thus, water will flow from the 15% solution to the 30% solution through the semipermeable membrane, illustrating the process of osmosis.
