    Counting Phase Phases
Click For Summary
SUMMARY

The discussion centers on Gibb's phase rule as it applies to a system of four immiscible liquids. The user initially believes there is one liquid phase but later concludes that each of the four components constitutes a separate phase. Applying Gibb's phase rule, F = C - P + 2, results in five degrees of freedom (F = 4 - 4 + 2 = 2), confirming that there are indeed four distinct liquid phases in the system.

PREREQUISITES

Hello,

I was wondering, suppose I had a mixture of a few liquids that were immiscible, say 4.

Now, when calculating the degrees of freedom, I am confused about the number of phases.

I think the number of components is 4, but the number of phases should be 1, liquid, right? Or does each component in the liquid phase count as one phase. I have seen problems that seem contradictory to what I think the answer should be

F = C - P + 2

F = 4 - 1 + 2 = 5
