Verified step by step guidance

1. Identify the characteristics of strong electrolytes, weak electrolytes, and nonelectrolytes.
2. Examine the diagrams to determine the degree of ionization or dissociation of each substance in solution.
3. For a strong electrolyte, look for complete dissociation into ions in the diagram.
4. For a weak electrolyte, look for partial dissociation, with some molecules remaining intact.
5. For a nonelectrolyte, look for no dissociation, with all molecules remaining intact in the solution.

Key Concepts

Electrolytes

Electrolytes are substances that dissociate into ions when dissolved in water, allowing the solution to conduct electricity. They can be classified into strong electrolytes, which completely dissociate into ions, weak electrolytes, which partially dissociate, and nonelectrolytes, which do not dissociate at all. Understanding these classifications is crucial for analyzing the conductivity of solutions.

Strong vs. Weak Electrolytes

Strong electrolytes, such as sodium chloride, fully ionize in solution, resulting in high conductivity. In contrast, weak electrolytes, like acetic acid, only partially ionize, leading to lower conductivity. Recognizing the differences in ionization behavior helps in determining the nature of the substances AX, AY, and AZ in the given question.

Conductivity Testing

The conductivity of an aqueous solution is a practical method to identify electrolytes. Solutions with high conductivity indicate the presence of strong electrolytes, while low conductivity suggests weak electrolytes or nonelectrolytes. By observing the conductivity of the solutions represented in the diagrams, one can classify AX, AY, and AZ accordingly.
