Explanation:

Complete the Frayer Model for Solute

Using the Solute and Solvent, Frayer Model, and Vocabulary Graphic Organizer knowledge points

• Definition: A substance that is dissolved in a solvent to form a solution.
• Illustration: A sketch showing solid particles (solute) being added into a beaker of liquid.
• Example: Salt (sodium chloride), sugar.
• Sentence: The solute dissolved completely in the warm water.

Complete the Frayer Model for Solvent

Using the Solute and Solvent, Frayer Model, and Vocabulary Graphic Organizer knowledge points

• Definition: A substance, typically a liquid, that dissolves a solute to form a solution.
• Illustration: A sketch of a beaker filled with liquid molecules ready to surround solute particles.
• Example: Water, ethanol.
• Sentence: Water is known as the universal solvent because it dissolves many substances.

Complete the Frayer Model for Solution

Using the Chemical Solutions, Frayer Model, and Vocabulary Graphic Organizer knowledge points

• Definition: A homogeneous mixture composed of two or more substances, where a solute is dissolved in a solvent.
• Illustration: A sketch of a beaker containing a completely uniform, clear liquid mixture.
• Example: Saltwater, air.
• Sentence: The salt and water mixed thoroughly to form a clear solution.

Complete the Frayer Model for Soluble

Using the Solubility, Frayer Model, and Vocabulary Graphic Organizer knowledge points

• Definition: Capable of being dissolved, especially in a liquid solvent.
• Illustration: A sketch showing solid crystals breaking apart and dispersing evenly throughout a liquid.
• Example: Sugar in water, table salt in water.
• Sentence: Sugar is highly soluble in hot tea.

Complete the Frayer Model for Insoluble

Using the Insoluble Substances, Frayer Model, and Vocabulary Graphic Organizer knowledge points

• Definition: Incapable of being dissolved in a liquid solvent.
• Illustration: A sketch showing solid particles settling at the bottom of a beaker filled with liquid.
• Example: Sand in water, oil in water.
• Sentence: Sand is insoluble in water and will settle at the bottom of the container.

Answer:

Question 1: Solute

• Definition: A substance that is dissolved in a solvent to form a solution.
• Illustration: A sketch showing solid particles (labeled "solute") being poured into a beaker of liquid.
• Example:

1. Salt (sodium chloride)
2. Sugar

• Sentence: The solute dissolved completely in the warm water.

Question 2: Solvent

• Definition: A substance, typically a liquid, that dissolves a solute to form a solution.
• Illustration: A sketch of a beaker filled with liquid (labeled "solvent") before any solute is added.
• Example:

1. Water
2. Ethanol

• Sentence: Water is known as the universal solvent because it dissolves many substances.

Question 3: Solution

• Definition: A homogeneous mixture composed of two or more substances, where a solute is completely dissolved in a solvent.
• Illustration: A sketch of a beaker containing a completely uniform, clear liquid mixture with no visible solid particles.
• Example:

1. Saltwater
2. Apple juice

• Sentence: The salt and water mixed thoroughly to form a clear solution.

Question 4: Soluble

• Definition: Capable of being dissolved, especially in a liquid solvent.
• Illustration: A sketch showing solid crystals breaking apart and dispersing evenly throughout a liquid.
• Example:

1. Sugar in water
2. Coffee granules in hot water

• Sentence: Sugar is highly soluble in hot tea.

Question 5: Insoluble

• Definition: Incapable of being dissolved in a specific liquid solvent.
• Illustration: A sketch showing solid particles remaining intact and settling at the bottom of a beaker filled with liquid.
• Example:

1. Sand in water
2. Chalk powder in water

• Sentence: Sand is insoluble in water and will settle at the bottom of the container.
