Which property indicates the ability of a substance to be dissolved?

The correct answer is "soluble" because this term specifically describes the capability of a substance to dissolve in a solvent to form a homogeneous solution. When a substance is labeled as soluble, it means it can be mixed with a solvent (like water) and will disperse at a molecular level, leading to an even distribution throughout the solution.

"Solubilization," while related, refers to the process of making a substance soluble. It describes the steps or mechanisms involved in achieving solubility but does not directly answer the question about the characteristic of the substance itself.

"Saturation" pertains to a state in which a solvent has dissolved the maximum amount of solute possible at a given temperature; thus, it indicates not just solubility but also the limits reached within that solvent.

"Solvent" refers to the substance (often liquid) in which the solute is dissolved, like water or alcohol, rather than describing the property of the solute itself.

Understanding the terminology is crucial, as "soluble" clearly identifies the ability of a specific substance to dissolve, making it the most appropriate choice for this question.
