Since most solutes have a limited solubility in a given amount of solvent at a fixed temperature (i.e. are not miscible), the temperature of the solvent generally has a marked effect on the amount of solute that will dissolve. For most solids dissolved in liquids, the dissolving process is endotherm ...
