What are the differences and similarities between concentration and solubility?
1. Concentration is amount of solute dissolved in a unit quantity (mass or volume) of a solution. Whereas solubility is the maximum amount of the solute that can be dissolved in a given amount of the solvent.
2. Concentration is expressed as percent by weight or volume, mole fraction, molarity etc. Solubility is the ability of a solute to dissolve in a solvent at given temperature and pressure. It is expressed as grams/litre or moles/litre.
3. Based on concentration a solution can be saturated, unsaturated or supersaturated. Based on solubility the solutes are soluble or insoluble, miscible or immiscible.
4. Concentration and solubility are both temperature dependent.
