What factors affect the solubility of a solid?

Answer 1

The solubility of a solid is affected by the temperature of the solvent, by stirring the solution, and by the degree to which the solid has been broken up into smaller pieces (a finely powdered solid dissolves most easily, of all possible solid forms). The specific solvent being used to dissolve the solid is also obviously a factor, and so is any other solute that is being dissolved simultaneously into the same solvent. Salts make other salts more soluble, a phenomenon with the charming name of "salting in".
