Water solubility, as defined in the material, refers to the degree to which a substance will

• A. Mix with water.
• B. Dissolve in water.
• C. React with water.
• D. Conduct electricity in water.

Answer: (A)

The concept being tested is how water solubility is defined in the material. In that reference, solubility is described as the degree to which a substance will mix with water to form a uniform, single phase. This focuses on the substance’s ability to blend with water and distribute evenly, which is the essence of solubility in this context. While dissolution is the process by which a substance becomes part of the water, the material uses mixing capacity as the measure of solubility. Reacting with water describes a chemical reaction rather than solubility, and conducting electricity in water relates to how well the dissolved material conducts electricity, not whether it dissolves or mixes at all.
