Why Is It Good To Use The Stemless Funnel For This Technique?
Asked by Janet Franklin|August 7, 2021
Why should you use a stemless funnel for hot gravity filtrations during a recrystallization? Stemless funnels should be used, because with long-stemmed funnels, the crystals come out in the stem as the solution cools, blocking up the funnel.

Why is it good to use the stemless funnel for hot gravity filtration? With long-stemmed funnels, the crystals come out in the step as the solution cools, blocking up the funnel. Using a stemless funnel prevents this from happening.
Why is it good to use a stemless funnel for hot gravity filtration?
A stemless funnel is used because crystals can form in the cool stem of a long-stem funnel and clog it. It is important that the glass setup is warm before starting the filtration.
What was the purpose of recrystallizing the Acetophenetidin?
What is recrystallization? It is technique to purify organic solids by removing the impurities in it. Impurities hinder the crystal lattice structure of these compounds.
Why is it important not to dilute the initial sample?
The least polar compound will elute first. Why is it important not to dilute the initial sample before it has been loaded onto the chromatography column? It is important to ensure that the entire sample enters the column in as compact of a band as possible.
What is the purpose of Salicylamide?
Salicylamide (o-hydroxybenzamide or amide of salicyl) is a non-prescription drug with analgesic and antipyretic properties. Its medicinal uses are similar to those of aspirin. Salicylamide is used in combination with both aspirin and caffeine in the over-the-counter pain remedy PainAid.
Can IR spectroscopy be used to distinguish 2 pentanone from 2 hexanone?
Can IR spectroscopy be used to distinguish 2-pentanone from 2-hexanone? No, because IR is used to distinguish b/w functional group.2-pentanone will have 4 signals and 2-hexanone will have 5.
