Solution
Solution Steps
Step 1: Understanding Solubility
Solubility refers to the property of a substance to dissolve in a solvent. It is typically quantified as the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.
Step 2: Analyzing Each Option
The ability of the substance to dissolve in water: This describes a general property but does not quantify the solubility.
The ability of the substance to dissociate into ions when dissolved in water: This describes ionization, not solubility.
The maximum amount of a substance that can dissolve in a specific amount of solvent: This accurately describes solubility.
The mass of solvent necessary to completely dissolve 100 g of the substance: This is a specific case and not a general definition of solubility.
Final Answer
The best description of solubility is:
\[
\boxed{\text{the maximum amount of a substance that can dissolve in a specific amount of solvent}}
\]
