When the glucose solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level rises. Based on this information, what can be said about these two solutions?
a.) The unknown solution had the lower concentration.
b.)The unknown solution had the higher concentration.
c.)The two solutions have the same concentration.
I'll say its A, since when u put in the soln, it rised, meaning it was lwoer in conc. but ive been wrong.
Answered below.
higher concentration
To determine the answer, let's understand what is happening in this experiment and how osmosis works. Osmosis is the movement of solvent molecules, in this case, water, from an area of lower solute concentration to an area of higher solute concentration through a semipermeable membrane.
In this case, the glucose solution is placed in a container separated by a semipermeable membrane from an unknown solution. When the two solutions are connected, the level of the unknown solution rises.
Based on this information, we can conclude that the unknown solution has a higher solute concentration than the glucose solution. Here's why:
The rise in the level of the unknown solution indicates that water has moved from the glucose solution into the unknown solution through the semipermeable membrane in an effort to equalize the concentration of solutes on both sides. This movement of water is driven by the higher solute concentration in the unknown solution, as water tends to move from areas of lower solute concentration to areas of higher solute concentration.
Therefore, the correct answer is:
b.) The unknown solution had the higher concentration.
It's important to note that osmosis is influenced by solute concentration, not just the volume or level of the solution. So, even though the level of the unknown solution rose, it doesn't necessarily mean its initial volume was larger. Concentration is a measure of the amount of solute dissolved in a given volume of solvent.
