Osmosis Worksheet illustrating water movement in various concentration gradients.

Problem Description:

The task involves analyzing osmosis in various solutions. The worksheet provides different beakers with varying concentrations of water and solute (e.g., salt). The goal is to:

1. Draw arrows indicating the direction of water movement by osmosis.
2. Fill in any missing percentages for water or solute.
3. Identify the type of solution (hypertonic, hypotonic, or isotonic) based on the concentration differences.

Solution Approach:

#### Step 1: Understand Osmosis
- Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration through a semipermeable membrane.
- Water moves to balance the solute concentration on both sides of the membrane.

#### Step 2: Analyze Each Beaker
We will analyze each beaker step by step, filling in missing values, determining the direction of water movement, and identifying the type of solution.

Beaker Analysis

#### Beaker 1:
- Left Side: 90% H₂O, 10% solute
- Right Side: 85% H₂O, 15% solute
- Missing Values: None
- Water Movement: Water moves from the left side (lower solute concentration) to the right side (higher solute concentration).
- Type of Solution: Hypertonic (right side) relative to the left side.
- Arrows: Left → Right

#### Beaker 2:
- Left Side: 80% H₂O, 20% solute
- Right Side: 70% H₂O, 30% solute
- Missing Values: None
- Water Movement: Water moves from the left side to the right side.
- Type of Solution: Hypertonic (right side) relative to the left side.
- Arrows: Left → Right

#### Beaker 3:
- Left Side: 45% H₂O, 55% solute
- Right Side: 55% H₂O, 45% solute
- Missing Values: None
- Water Movement: Water moves from the right side to the left side.
- Type of Solution: Hypertonic (left side) relative to the right side.
- Arrows: Right → Left

#### Beaker 4:
- Left Side: 75% H₂O, 25% solute
- Right Side: 65% H₂O, 35% solute
- Missing Values: None
