Question

Draw a phase diagram showing how the phase boundaries differ for a pure solvent compared with a solution.

Accepted Answer

Hello everyone. So in this video we're given four different diagrams and we want to find the one that depicts the distinction between the face boundaries of a peer solvent and a solution. So the requirements for this, let's go ahead, write this out. One of them being that the vapor pressures will just simplify that to VP of the solution is lower then the pure solvent. And this means that the boiling point would also apply to BP of this solution is higher. Then the pure solve it. So taking a look at our first choice here. This first diagram um eight we can see that the liquid vapor phase so this and this this transition line is lower than the solution of the solvent. So this line is lower than this one right here. Another thing to point out that we can see that triple point. So these points here, the triple point of the solution is also lower and then our solid liquid line. So this and this. It's lower on the X axis which is also the temperature, which means that the boiling point of the solution is also lower. So all of these that we just described for our requirements here do fit this as a choice. A and because we already found our um diagram a fix fits all these requirements here, we all need to go ahead and continue on because we found the one then that's going to be my final answer for this problem
