Salt Water Phase Diagram
Eg salt water molten na 2o sio 2 gaseous state seemingly only one phase occurs gases always mix liquid state often only one phase occurs homogeneous solutions solid state. The phase diagram of water is complex a b c e f having a number of triple points and one or possibly two critical points.

Phase diagrams for binary solutions are more complicated because they have an extra dimension composition.

Salt water phase diagram. In a phase diagram for a pure component solid liquid vapor liquid solid vapor and solid solid equilibria can be shown in the same diagram. The phase diagram is interpreted in just the same way except that this time salt crystals are formed at first rather than ice crystals. At some point the rate of vaporization and the rate of condensation become equal and the system is at equilibrium.
It is below about 27 the system will decompose into salt free ice and liquid water with an increased salt concentration as shown for the red composition around 18 salt the last drop to solidify will do so at 211 o c. Ice floats in liquid water. Critical points are usually found at the high temperature end of the liquid gas phase line.
Notice one key difference between the general phase diagram and the phase diagram for water. The phase diagram of water. At temperatures above the critical temperature a gas cannot be liquefied.
Cooling salt solution more concentrated than the eutectic composition. Phase diagrams for salt solutions. This page looks at the phase diagram for mixtures of salt and water how the diagram is built up and how to interpret it.
This is not possible for a binary system. The reason is that water is an unusual substance in that its solid state is less dense than the liquid state. Ftsalt fact salt phase diagrams 338 click on a system to display the phase diagram.
Sodium chloride and water form a eutectic mixture whose eutectic point is 212 c and 233 salt by mass. The eutectic nature of salt and water is exploited when salt is spread on roads to aid snow removal or mixed with ice to produce low temperatures for example in traditional ice cream making. Many of the crystalline forms may remain metastable in much of the low temperature phase space at lower pressures.
In the next diagram the first salt crystals will form when the temperature hits the boundary line. Cooling salt solution with the eutectic composition. A phase is a homogeneous portion of a system with uniform physical and chemical characteristics in principle separable from the rest of the system.
Cooling salt solution more dilute than the eutectic composition. Phase diagram of salt water. When molecules in the gas phase collide with the liquid surface they loose energy and return to the liquid.
If your salt concentration is for example lower than the eutectic concentration ie. In waters diagram the slope of the line between the solid and liquid states is negative rather than positive.
