Hi everyone, i was thinking about a simple concept, miscibility. But what confused me is what determines 2 liquids are miscible or not. What property does miscibility rely on?
1) densities of the 2 liquids are close to each other
2) molecules of one liquid can fit into spaces between the molecules of the other liquid
What examples are there of miscible liquids that have densities not close to each other?
Edit: I have one more question and i feel maybe i should combine them into one post to save space on the forum.
In a fixed volume container with 2 gases, is the mole fraction of a gas equal to the partial pressure ratio of it? Considering ratio values only and not the actual values. I am only aware that mole fraction equals to volume ratio, but since volume and pressure are linked, can mole fraction be related to partial pressure?
