Question
distillation of methanol and water mixture experiment
Graph the data from each table below.
describe the two graphs and any differences you observe between the two.
from your graphic data, identify the experimental biling point of methanol.
look up the accepted boiling point for methanol(cite reference). compare your experimentally determined boiling points with the literature value for methanol
if there is a difference in observed boiling points for the two distillations methods, explain why one distillation is more accurate than the other.
