The density of diethyl ether, an organic solvent, is 0.706g/cm3. If you mix 50 mL water and 50 mL diethylether together in a separatory funnel, which layer would be ontop?
Homework Answers
density of water is 1g/cm3 & density of diethylether is .706g/cm3. Because diethyl ether isless dense than water (diethyl ether's density issmaller), It will be on top.

An unknown compound followed by 4.0 mL of diethyl ether were mixed and transferred to a separatory funnel. 2.0 mL of 1.0 m NaOH were added to the funnel, the bottom aqueous layer was removed and placed into an erlenmeyer flask labled NaOH extract 1, another 2.0 mL was added to the funnel and the lower aqueous layer was put into a second flask labled NaOH extract 2. The ether layer was left in the flask. 1. What compound was...

1. What experimental difficulty would you encounter if you had neglected to include a drying step before evaporating the ether solution of the neutral organic compound? 1b. An extraction procedure specifies that an aqueous solution containing dissolved organic material be extracted twice with 10-mL portions of diethyl ether. A student removes the lower layer after the first extraction and adds the second 10-mL portion of ether to the upper layer remaining in the separatory funnel. After shaking the funnel, the...
