this technique is used to separate liquids with different boiling points?

Distillation... if the liquids have boiling points within 100 degrees celsius, then fractional distillation should be used.  Otherwise, simple distillation is a lot easier.

Miscible liquids are ones that mix in all proportions, for example vinegar and water.  You are not able to see separate phases when you mix these two together, not like when you mix oil and water.\n\nhydrocarbons for example may be used for enhanced oil recovery.  A good website to look at is listed below.\n\nPlease remember that you can never ask too much =) It always helps us to learn the more questions we ask.

Chromatography is a means of separating molecules in a solution.  A very widely used technique is high-performance liquid chromatography (HPLC) which can use dozens of different separation columns to separate anything from small molecules to very large proteins, DNA and RNA.  In addition, the different fractions coming off the column can be collected and purified.  An example is that one can load spider venom onto the column, and each fraction collected and tested, and this way you can find out how many different toxin and poisons are present, what they are, and what the relative abundance of each are.

test the reactions of different substances in water. like um put in sugar and salt and then say it dissolved. And put in oil and say it freakin stayed seperate or whatever it does

You might need to do a fractional distillation, but I'm not sure how you'd get the equipment. The idea is that you have a heat source, something to put the liquid in, a fractional column on top of that, that the material has to pass through, and then a cold-water condensor beyond that, to condense the distillate.

When what is mixed is not fully disolved into the liquid medium.  It usually settles.  A cenrifuge will not separate out the components that are not part of the solution.

one generally uses pure water as a base point. other liquids are typically refrenced as lighter or heavier than water.

You measure as a percentage of time longer it takes to separate the water out from oil than a control test of half water half oil mix. For example you mix 1 liter oil with 1 liter water (heated to 100oC and thoroughly mixed), then measure the time it takes to separate the water completely from oil. Then separate the oil you wish to calculate. The time taken longer, as a percentate, is the measurement. We do this using a ASTM D1401 machine - look this up on the web for more details.

I don't know that you can, different solvents react differently to pressure, so I don't think it's a one eqaution fits all kind of process.  That's why they all have different graphs for phase vs temperature/pressure.  I'm sorry.\nSounds like you have a pretty high boiling point though, the things I've taken off that had to be real high temp were water, toluene, and pyridine.  Could it be one of them?  They smell pretty different, so you'd know which.  \nThat's an interesting question though, I've never stripped a solvent that I didn't know what it was.

depends if the mixture is bonded by a physical or chem bond....there is magnetic separation,distillation,fractional distillation,evaporation,crystallization...etc...why dont u look up a chemistry book

method of separating components of substances: the use of biological agents such as plants, enzymes, or biological membranes to separate components, e.g. in the purification of proteins or water or in the manufacture of food and pharmaceuticals

By fractional distillation.\nDEG distills at 93 'C, you can collect first and then collect water at 100 'C.

To perform a solution-based separation, you need a solvent in which one or some of the solutes (in the mixture to be separated) is/are highly soluble, and in which the other components are highly insoluble.\n\nA simple example might be separating an ethanol/pentane mixture by using water.  Ethanol, being polar, will readily dissolve in water; but the nonpolar pentane will not.

It depends on the type of alcohol and whether its single component or multicomponent based. if it is simple and short chain alcohol (low boiling pt) by simple distillation it can be separated.  If there are mixture of alcohols and long chained then you need to convert them into ester/salt, which would ease the separation process.

An apparatus for reflux uses a round bottom flask for boiling the reaction contents and allowing the vapours to condense in a water cooled condenser attached vertically above the flask.  The vapours condense and run back down into the flask in order for them to boil again.\n\nIt is a method for boiling a solvent, or mixture, under conditions of near constant volume without the need to "top up" the vessel with fresh solvent.

To purify (separate) the product you want from impurities. For example, if you wanted to separate a mix of alcohol and water, you would use the distillation flask along with a heating mantle (like a Bunsen burner, but designed for flasks) to heat the mixture; because alcohol has a lower boiling point than water, it would evaporate faster and re-condense in the collection flask, leaving water in the distillation flask.
