Which of the following is an example of a nonaqueous solution?

• A. Sodium chloride dissolved in water
• B. Copper sulfate dissolved in water
• C. Sugar dissolved in water
• D. Sulfur dissolved in carbon disulfide

Answer: (D)

Verified step by step guidance

1. Understand the definition of a nonaqueous solution: it is a solution where the solvent is not water.
2. Identify the solvent in each given example. For sodium chloride, copper sulfate, and sugar dissolved in water, the solvent is water, so these are aqueous solutions.
3. Recognize that sulfur dissolved in carbon disulfide uses carbon disulfide as the solvent, which is not water.
4. Conclude that since the solvent in the last example is not water, it is a nonaqueous solution.
5. Therefore, sulfur dissolved in carbon disulfide is an example of a nonaqueous solution.
