I did a lab for Organic Chemistry
We did a simple distillation of an unknown alcohol to determine the boiling point, which was found to be 74*C
The four possibilities for the unknown were methanol, ethanol, 1-propanol and 2-propanol. So from the boiling point the unkown must be ethanol...
We then did a fractional distillation of this alcohol mixed with water. The alcohol was distilled off after 4.0 mL (25.0 mL of mixture was used).
beginning percent composition of unknown/H20
would this be :
Does it form any azeotrops, list them:
does this mean binary with water etc., ternary...? or am I supposed to write some other description?
If it did form an azeotrops Calculate the beginning % composition of the mixture
confused about this...
Any help would be greatly appreciated!
