what is the procedure for simple distillation? (plz tell in points) for my holiday homework i need it ASAP

Explanation:
Simple distillation is a procedure by which two liquids with different boiling points can be separated. Simple distillation (the procedure outlined below) can be used effectively to separate liquids that have some major degrees difference in their boiling points. As the liquid being distilled is heated, the vapors that form will be richest in the component of the mixture that boils at the lowest temperature. Purified compounds will boil, and thus turn into vapors, over a relatively small temperature range (2 or 3°C); by carefully watching the temperature in the distillation flask, it is possible to affect a reasonably good separation.
As distillation progresses, the concentration of the lowest boiling component will steadily decrease. Eventually, the temperature within the apparatus will begin to change; a pure compound is no longer being distilled.
A Simple Procedure is there. First, we need to know some basic details about the mixture;
The boiling point of each component
Vapor pressure of Each component
The volume of Each component
Some basic know-how about the system
After knowing all these details, we will Do distillation of Seawater.
Since we all know the Boiling point of water is 100 oC, we will heat the solution up to 100 oC and start collecting Vapor phase pure water in the flask.
We will continue keeping the solution at 100 oC till we receive water in the Flask.
As the water vapor will decrease at the completion of distillation, we will stop distillation and collect pure water in the flask.
The residue, in this case, is Sea Salt. which will not evaporate at 100 oC.
Binary Distillation is completed.
Total time for Binary distillation relies on Vapor pressure of each component, Total volume of solution.
Simple distillation is effective only when separating a volatile liquid from a nonvolatile substance. If the liquids comprising the mixture that is being distilled have boiling points that are closer than 50 degrees to one another, the distillate collected will be richer in the more volatile compound but not to the degree necessary for complete separation of the individual compounds.
