Bacterial contamination : Without preservatives, bacteria grow in liquid solutions
(For more information about vapor pressure, see Chapter 11 "Liquids", Section 11.3 "Unique Properties of Liquids".) We can represent these opposing processes as follows: Equation 13.4 Although the terms precipitation and crystallization are both used to describe the separation of solid solute from a solution, crystallization refers to the formation of a solid with a well-defined crystalline structure, whereas precipitation refers to the formation of any solid phase, often one with very small particles

The theoretical maximum amount in solution is determined by the relative amounts of its pH-dependent unprotonated and protonated forms and follows the Henderson-Hasselbalch and precipitation-pH (pHp) models ( Figures 3 , and S4, S5, in Supplemental Information )
