The diagram shows two solutions of glucose and salt in an open U-tube apparatus containing a semipermeable membrane (which allows the passage of glucose, salt, and water). Which of the following accurately describes what will take place next?
Understand the Problem
The question is asking about the behavior of solutions in a U-tube apparatus equipped with a semipermeable membrane, specifically what will occur after the glucose and salt solutions are placed in the apparatus. This involves concepts from osmosis and diffusion.
Answer
Water will move towards the higher solute concentration side.
Water will move towards the side with the higher concentration of solute (either glucose or salt) through osmosis.
Answer for screen readers
Water will move towards the side with the higher concentration of solute (either glucose or salt) through osmosis.
More Information
In an open U-tube with a semipermeable membrane, water will move through osmosis from the side with lower solute concentration to the side with higher solute concentration. Solutes such as glucose or salt can influence this movement.
Tips
A common mistake is assuming solutes will move easily across the membrane. Ensure understanding that the semipermeable membrane can allow or restrict certain molecules, impacting the direction of substance movement.
