Water Movement and Solution Concentration

The video tutorial explains the movement of water in relation to solute concentration, focusing on the concepts of hypotonic, hypertonic, and isotonic solutions. It provides practice problems to illustrate how water moves towards areas of higher solute concentration, using both percentage and molarity calculations. The tutorial also covers how to determine the type of solution based on solute and solvent percentages.

What is the primary rule for determining the direction of water movement in relation to solute concentration?

• Water does not move in relation to solute concentration.

• Water moves randomly.

• Water moves towards higher solute concentration.

• Water moves towards lower solute concentration.

In a scenario where the cell has 50% solute and the surrounding solution has 25% solute, where will the water move?

• Water will move in both directions equally.

• Water will move out of the cell.

• Water will move into the cell.

• Water will not move.

If a solution has less solute than the cell, what type of solution is it considered?

• Neutral

• Hypotonic

• Isotonic

• Hypertonic

When comparing a 20 molar solution in a cell to a 35 molar solution in the surrounding water, where will the water move?

• Water will move out of the cell.

• Water will not move.

• Water will move into the cell.

• Water will move in both directions equally.

What does the 'M' next to a numerical value for solute indicate?

• Molecular weight

• Molar mass

• Moles per liter

• Mass

In a solution with 90% solvent and 10% solute, and a cell with 70% solvent and 30% solute, where will the water move?

• Water will move in both directions equally.

• Water will move out of the cell.

• Water will move into the cell.

• Water will not move.

If a solution is hypotonic compared to the cell, what does this imply about the solute concentration?

• The solution has more solute than the cell.

• The solution has the same solute concentration as the cell.

• The solution has less solute than the cell.

• The solution has no solute.

How do you calculate the percentage of solute if you know the percentage of solvent?

• Add the solvent percentage to 100.

• Subtract the solvent percentage from 100.

• Multiply the solvent percentage by 100.

• Divide the solvent percentage by 100.

In a solution with 25% solute and a cell with 30% solute, what type of solution is the surrounding water?

• Neutral

• Isotonic

• Hypotonic

• Hypertonic

What is the net movement of water when the solute concentration is higher inside the cell than outside?

• Water does not move.

• Water moves out of the cell.

• Water moves in both directions equally.

• Water moves into the cell.
