8. After shaking and venting the separatory funnel, a student put the funnel on an iron ring. Worried that the product would evaporate, the student kept the hollow stopper on the funnel. After several minutes the student saw two layers had completely separated and opened the stopcock to drain the bottom layer, but no liquid drained out. What would you recommend that the student do?
Homework Answers
Please remove the stopper , so that vacuum is releases and then open the stopcock to drain the bottom layer.
By removing the stopper air pressure is enter in the separating funnel and push the liquid to drain through the stopcock.

While performing a liquid/liquid extraction in a separatory funnel, a student placed the separatory funnel on the ring stand right after shaking it. The student forgot to take the stopper off the top of the separatory funnel after shaking it and before draining one of the layers. Why is this a bad idea?

PROCEDURE Preparation oft-Pentyl Chloride In a 125-mL separatory funnel, place 10.0 mL of tert-pentyl alcohol (2-methyl-2- butanol, MW = 88.2, d = 0.805 g/mL) and 25 mL of concentrated hydrochloric acid (d 1.18 g/mL). Do not stopper the funnel. Gently swirl the mixture in the separa- tory funnel for about 1 minute. After this period of swirling, stopper the separatory funnel and carefully...

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

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.

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...
