Separating Components of a Mixture by Extraction

Рет қаралды 605,279

5 жыл бұрын

When we perform a chemical reaction, we are usually trying to get a particular molecule. But when we are done with the reaction, there will probably be a bunch of different stuff in the reaction flask. How do we get just the thing we want and not the other stuff? It's actually pretty involved, with a couple different steps, but the first of these will always be extraction using a separatory funnel. Let's learn how to do this!

Outstanding video and explanation! I did a PhD in organic chemistry many years ago and I'm now in my 9th year of secondary teaching, planning an A-level lesson - Wow do I wish your videos were around when I was at Uni!

Hello Dr Louise, is this a possible method to extract organochlorine concentration, Im doing a research for my thesis, and its about occurence of OCPs level of concentration in a river.

Hi, I have a question about extraction, if you could help. How would we go about seperatign alcohol and carboxylic acid. More specifically, I am talking about napthol and terphthalic acid. I just don't understand this becuase every video I watch always seperates one acidic, one basic, and one neutral compound.

In an OC lab course the lab assistant provided a good life hack: if you're unsure which layer is which, just draw a line with a marker where both layers meet. Add a little water: if the level of the seperating line remains in line with your marking, then water is the upper layer. If it is raised, water is at the bottom
