The maximum amount of a solid solute that can be dissolved in a specified amount of a given liquid solvent does not depend upon -

1. Temperature 2. Nature of solute
3. Pressure 4. Nature of solvent
Hint: Solids are incompressible 
The maximum amount of solid that can be dissolved in a specified amount of a given solvent does not depend upon pressure. This is because solid and liquid are highly incompressible and practically remain unaffected by changes in pressure.
