help!can anyone answer my question!
it is the experiment that i did in school!~
topic:boiling point with composition for different mixtures of two miscibe liquids
first: mixing trichloromethane and ethyl ethanoate
so the following is the result~
Volume of trichloromethane/cm3
10 10 10 10 5 2 0
Volume of ethyl ethanoate/cm3
0 2 5 10 10 10 10
Volume % of ethyl ethanoate
Boiling point/0C
60 65 70 68 67 66 63
by plotting boiling point against volume %of ethyl ethanoate . we can see the curve rise but after drop , so why this happen !~??/
can anyone explain in detail ?
help me please!~
