Discuss what will be observed as a sample of water is taken along a path in its phase diagram that encircles and is close to its critical point.

Solutions

Expert Solution

As we know Critical point is the end point of the phase equilibrium curve.

(the critical point of water occurs at around 647 K and 22.064 MPa)

Therefore, It is observed that in the vicinity of the critical point, the physical properties of the Vapour and the liquid change dramatically, with both phases becoming ever more similar .

But the liquid water under normal conditions is nearly incompressible, has a high dielectric constant, has a low thermal expansion coefficient, and is an excellent solvent for electrolytes.

And Near the critical point, all these properties changes as water becomes compressible,a poor dielectric expandable, a bad solvent for electrolytes, and prefers to mix with organic molecules and non-polar gases.

A surface water sample of 50 ml was taken to determine the concentration of an organic pollutant in the sample. An organic solvent was used as extracting solvent. On analysis of both phases by GC-MS, the pollutant concentration (mass/vol based) in the organic phase was 5 times that found in the aqueous phase. If after the second extraction (each using 50ml fresh organic solvent) the concentration of pollutant in the organic phase was 18 ppm (mass basis), determine the initial...
