notice how i've been careful to say an alcohol rich phase and a water rich phase i haven't just called it alcohol and water that's because whenever you mix two liquids together the liquids are either going to form one miscible solution together meaning that it's one liquid not two phases but just one or it can separate out into two phases like this and when it separates out into two phases it's not like one is completely alcohol and the other is completely water but what it is is one of them will have more of one molecule than the other one so this phase has more alcohol than water and this one has more water than alcohol and the state that takes the least energy for the molecules is for them to separate into two liquid phases this is the same for an oil water mixture as well it's just that they separate out into two liquid phases where one is almost completely oil and the other one's almost completely water so we usually just call it oil and water even though in both phases there's oil and water we can test this out by putting our beads in here again you can see they float right in the middle there the blue beads are less dense than salt water but more dense than alcohol and the white beads are more dense than alcohol but less dense than salt water and so both of them separate according to their density this technique of separating water from alcohol using salt is called salting out and it's a technique used in chemistry a lot whenever you want to separate out organics from water hey everyone thanks for watching another episode of the action lab i hope you enjoyed it if you did don't forget to subscribe if you haven't yet and you can also hit the bell so that you can be notified when i release my latest video and check out the URL_TOKEN for the action lab experiment boxes and check out my shorts channel if you haven't yet it's a second channel that i have where i do videos similar to this one it's called action lab shorts but i do them in less than a minute and thanks for watching and i'll see you next time
