What is the difference between miscibility and solubility?

Miscibility refers to the ability of two substances to mix together in any proportion to form a homogeneous solution, regardless of their chemical properties. Solubility, on the other hand, specifically refers to the ability of a solute to dissolve in a solvent to form a solution. In simpler terms, miscibility is about how well two substances can mix together, while solubility is about how well one substance can dissolve in another.
