What is a characteristic of a strongly soluble substance?

A characteristic of a strongly soluble substance is that it dissolves readily in a solvent. This means that when the substance is added to a solvent, a significant amount of it will dissolve, resulting in a homogeneous solution. The ability of a substance to dissolve easily indicates that the intermolecular forces between the solute and solvent are favorable, allowing for effective solvation and the formation of a solution.

In contrast, other options describe scenarios that are not indicative of strong solubility. For instance, a substance that does not dissolve in liquid suggests poor solubility, while a solubility of less than 1g per 100g of solvent signifies that the substance is only slightly soluble. Additionally, a characteristic of only dissolving at high temperatures indicates a temperature-dependent solubility, which is not aligned with the behavior of strongly soluble substances that dissolve readily under normal conditions.
