Diethyl ether was a very volatile liquid and its fumes could be seen as it was transferred from its holding container to the beaker. We then added the solution to a separatory funnel and 6.8 ml of NaOH were also added. The funnel was then shaken and the solutions allowed to separate. One slight “error” we encountered was we forgot to open the valve to release the pressure caused by the solutions inside, causing our cap to pop off the funnel. Luckily no solution was lost on the process. After the solutions settled, the organic and aqueous phase were differentiated by a very small middle “phase” that looked like a contact lens since they refracted the light differently. All solutions,
