- a The process of surrounding solute particles with solvent particles to form a solutions; occurs only where and when the solute and solvent particles come in contact with each other.
- b The ratio of the number of moles of solute in solution to the total number of moles of solute and solvent.
- c The number of moles of solute dissolved per liter of solution.
