Phase diagram can be constructed that show the effect of more than two variables on the phase of a substance. Phase diagrams can use other variables in addition to or in place of temperature, pressure and composition, for example the strength of an applied electrical or magnetic field, and they can also involve substances that take on more than just three states of matter. One type of phase diagram plots temperature against the relative concentrations of two substances in a mixture called a "binary phase diagram", as shown at right. Such a mixture can be either a solid solution, eutectic or peritectic,
Extraction (chemistry) Extraction (chemistry) Extraction in chemistry is a separation process consisting in the separation of a substance from a matrix. It includes "Liquid-liquid extraction", and "Solid phase extraction". The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte move from the water into an organic layer. There exist several types of extraction, including: "liquid–liquid extraction", "solid-phase extraction",and "acid-base extraction." In liquid-liquid extraction compounds separate according to their relative solubility in two different immiscible liquid phases. This technique has been applied in several fields such as analytical chemistry
