The amount of solute dissolved in the solvent is its concentration . Chemistry 1110/1210 Dr Eric E. Moore Section 5.1 Section 5.2 Section 5.3 Section 5.4 Section 5.5 Section 5.6 Section 5.7 Section 5.8 Section 5.9 Section 5.10 Section 5.11 Section 5.12 Section 5.13 Concentration Concentration can be measured several ways, one is in terms of percent concentration , which is just the mass of the solute divided by the mass of the solute plus the mass of the solvent. A solution with a lot of solute in it is described as being concentrated and a solution with relatively little as being dilute . Chemistry 1110/1210 Dr Eric E. Moore Section 5.1 Section 5.2 Section 5.3 Section 5.4 Section 5.5 Section 5.6 Section 5.7 Section 5.8 Section 5.9 Section 5.10 Section 5.11 Section 5.12 Section 5.13 Saturation If you keep adding solute to your solution, and it doesnt dissolve (it remains solid and sinks to the bottom making a heterogeneous mixture), then the solution is described as saturated . If less solute is in solution than can be dissolved, a solution is unsaturated . Chemistry 1110/1210 Dr Eric E. Moore Section 5.1 Section 5.2 Section 5.3 Section 5.4 Section 5.5 Section 5.6 Section 5.7 Section 5.8 Section 5.9 Section 5.10 Section 5.11 Section 5.12 Section 5.13 Precipitation A solution that has more solute in it than a saturated solution is supersaturated . Solutions tend not to remain supersaturated long, and the excess solute separates into a different phase. When this different phase is a solid forming from a liquid solution, we describe the solid as a precipitate , and the process of the solid forming as precipitation . Chemistry 1110/1210 Dr Eric E....
