• A. Chemical property
• B. Physical property
• C. Thermal property
• D. Electrical property

Answer: (D)

Solubility describes how much solute can dissolve in a solvent at a given temperature. This is a physical property because it reflects how the material behaves without changing its chemical identity—the solute and solvent remain the same substances, just in a dissolved form. For example, when salt dissolves in water, you still have sodium chloride in solution; no new substance is formed unless a chemical reaction occurs. If a chemical reaction did take place during dissolution, that would be a chemical property. Solubility is not about how a substance conducts electricity or how it responds to heat in a way that changes it chemically, so it isn’t an electrical or thermal property.
