How many layers would you observe when dichloromethane and HCl (aq) are mixed in a separatory...
Homework Answers
It depends upon the density of two layers.
DCM has a density of 1.3 g/ml
aq/ HCl will ave density of <1.2 g/ ml
so when you mix both, less dense layer will be top side and more dense layer will be bottom side
hence upper layer will be aq. HCl layer
bottom layer will be DCM layer

The density of dichloromethane, an organic solvent, is 1.325 g/cm. If you mix 50 mL water and 50 mL dichloromethane together in a separatory funnel, which layer would be on top? The density of diethyl ether, an organic solvent, is 0.706 g/cm. If you mix 50 mL water and 50 mL diethyl ether together in a separatory funnel, which layer would be on top?

a) After the reaction is completed, the reaction mixture is
transfered to a separatory funnel. The layers are separated and the
organic layer is washed with each of the following: an equal amount
of saturand NaCl, satured NaHCO3, deionized H2O, and again with
saturated NaCl. This is an example of a "basic" work-up. Illustrate
what is being neutralized in this work up using a balanced
equation. (2 Marks)

Hello, I need help understanding a lab we are doing in class tomorrow. I need to know which is the "ORGANIC LAYER" ... we are using a separatory funnel, and I would like to know whether the organic layer will be on top or on the bottom. This is in order for me to correctly carry out the experiment. The lab is similar to this one I found online, and its very vague for me as to what is the...
