Moved from a technical forum, so homework template missing
From the list below, identiyfy what is present in the flask at each of the following times during the Dumas procedure performed with methanol:
Methanol (g)
Methanol (l)
Methanol (aq)
Air (g)
Water (l)
Water (g)
a) After the methanol is added and the flask is covered with foil?
b) Just before the flask is removed from the hot water bath?
c) When the flask is weighted after cooling?
My solution:
a) i think this would be methanol (l) and air (g) bc there is no evidence that methanol is in aq form
b) i think this would be methanol (g) bc all the air is expelled and the methanol is vapourized
c) this one i have no clue and don't even know how to reason out!
