When using a separatory funnel, you should vent the funnel. What does the term venting mean? Select one: Flipping the stopcock over quickly when draining the layers. Gently swirling the separatory funnel to help the layers settle after mixing. Opening the stopcock when the flask is inverted during mixing. Pouring the sample into the separatory ...
Step 1. The aim of the objective is to separate the following binary mixture. How would you separate the following binary mixture? mineral oil and water 1. Distillation sodium chloride and water 2. Filtration ethylene glycol and water 3. Liquid-liquid separation using a separatory funnel.
Question: Question 7 When shaking a separatory funnel (Select all that apply) A. the layers should not be allowed to mix B.the funnel should always be shaken without the stopper in place to prevent pressure buildup frequent venting through the stopcock is necessary to prevent pressure buildup D. the funnel should be inverted and cradled in the hand, with the palm of
Chemistry questions and answers. Washes and extractions are both techniques that use a separatory funnel to separate liquid layers.

Select one: Three-prong clamp on a ring stand Tripod stand Iron ring with wire gauze O Iron ring clamped to a ring stand When using a separatory funnel, you should burp the funnel.
The. Which of the following statement is correct? Select all that apply. Question 3 options: Separatory funnel can be used for separating miscible solvent mixture. The stem of the funnel should be pointed into a fumehood during the venting process to avoid spraying anyone with the contents of the funnel. Organic layer will always be the ...
Describe an experimental procedure that you could use to test whether or not a particular. 1)in a separation experiment using an aqueous solution and dichloromethane, which layer is on the bottom of the separatory funnel—the aqueous layer or the dichloromethane layer? What physical property allows you to determine this without doing the ...
Chemical Engineering questions and answers. Procedure 1. In a 125 mL separatory funnel, place 20mL of tert-pentyl alcohol (2-methyl-2-butanol) and 50 mL of concentrated HCI 2. DO NOT stopper the separatory funnel. Gently swirl the funnel until no reaction is observed. 3. Now stopper, invert the funnel, and open the stopcock to vent. 4.
Why does the separatory funnel need to be ‘vented’ every once in a while? (5 pts.) Was the organic layer on the top or the bottom of the separatory funnel? Why? (5 pts.) A crude non-acidic product mixture dissolved in ether contains acetic acid. Describe an extraction procedure to remove the acetic acid from the ether layer. (10 pts.)
