a. nonelectrolyte

Verified step by step guidance

1. Identify the characteristics of a nonelectrolyte: Nonelectrolytes do not dissociate into ions in solution, meaning they do not conduct electricity.
2. Examine the provided diagram: Look for a representation where molecules are intact and not separated into ions.
3. Consider the molecular structure: Nonelectrolytes typically consist of covalent compounds where atoms are bonded together without forming ions.
4. Analyze the image: Check if the diagram shows molecules that are not broken into ions, indicating a nonelectrolyte solution.
5. Select the diagram: Choose the one that best represents a solution where the solute remains as whole molecules, not dissociated into ions.

Key Concepts

Solute and Solvent

In a solution, the solute is the substance that is dissolved, while the solvent is the medium in which the solute dissolves. For example, in a saltwater solution, salt is the solute and water is the solvent. Understanding the roles of solutes and solvents is crucial for analyzing how solutions form and behave.

Electrolytes vs. Nonelectrolytes

Electrolytes are substances that dissociate into ions when dissolved in water, allowing the solution to conduct electricity. In contrast, nonelectrolytes do not dissociate into ions and do not conduct electricity. Recognizing the difference between these two types of solutes is essential for understanding the properties of solutions and their applications in chemistry.

Molecular Representation of Solutions

Diagrams representing solutions often use spheres to depict solute and solvent molecules. The size and color of the spheres can indicate different types of molecules, such as blue for solvent and red for solute. Analyzing these representations helps in visualizing how solutes interact with solvents at the molecular level, which is key to understanding solution chemistry.
