Which of the following best describes an electrolyte when dissociated in water?

• A. It produces ions that conduct electricity.
• B. It evaporates rapidly without interacting with water.
• C. It remains as neutral molecules and does not affect conductivity.
• D. It forms a precipitate that settles at the bottom.

Answer: (A)

Verified step by step guidance

1. Understand the definition of an electrolyte: An electrolyte is a substance that, when dissolved in water, dissociates into ions.
2. Recall that ions are charged particles, which can move freely in solution and carry electric current.
3. Recognize that the ability of a solution to conduct electricity depends on the presence of these free ions.
4. Evaluate the options given: only the option stating that the substance produces ions that conduct electricity matches the definition of an electrolyte.
5. Conclude that an electrolyte dissociates in water to produce ions, enabling the solution to conduct electricity.
