because hot water has higher energy and could induce a reaction of some kind depending on what solid you are using. In certain cases, it could make your solid go from being miscible to being soluble, in which case, this type of filtration would no longer be helpful.
Thanks for the vid! taking O chem 1, and prepping for lab. “Organic Chemistry Lab Techniques” by Lisa Nichols is an opensource resource we're referencing. vacuum filtration pg 55 suggest using a vacuum trap to prevent any potential back suction when connecting/disconnecting
gravity filtration is a slow tedious proces, vaccum filtration is fast, economic and almost dries the solid (filtrate?) completely. winning is for winners, build yourself a buchner funnel and make a suction pump from a 50ml syringe or bike pump.
If one wanted to use activated charcoal for filtering in addition to the filter in the Buchner funnel, what would be the best way to go about it? Would adding a layer of charcoal to the filter in the Buchner funnel be the best way to go about doing it? So when you pour the substance into the funnel, it first goes through the activated charcoal layer, THEN through the filter paper. Let me know what you think.
I woulkd add directly to the solution and stir or swirl around allowing it to come in contact with all your product in solution. Allow 20 mins or so. theres no reason bar econmic that youu couldnt filter through an activated charcoal layer as well!!
@@jhyland87 np. Mainly replying for future readers. The guy above talks about adding it directly to the solution but you might want both parts. Contaminating the solids and adding extra work if you want both parts (maybe you're dealing with something where you need yield from both etc) seems counterprodtice and you might want to add it after it goes through the solids filter.
Thank you, this is the only place I have found which has shown me what a water aspirator is!
thank you, it very useful and helps me a lot know about suction filtration

No shit

No gloves?
Can someone answer Suction filtration vs. Gravity filtration.
gravity filtration is a slow tedious proces, vaccum filtration is fast, economic and almost dries the solid (filtrate?) completely.

Coffee vs reverse espresso

It's a vacuum, you can basically add it at any point.
@@Atheism-And-Normative-Ethics yeah, I posted that 4 years ago, I now realize it was a silly question, lol

Wish to work in the lab after my graduation
Thank you very much
excellent job
yo why she got a watch on? what happened to no excess jewelry? Is she just too pro for us?!? Embarrassing
It's a college doing a stupid extraction video jackass
Bro wtf are you talking about?
you have helped a lot..thank you!
Thanks ❤
Wonderful
GREAT GREAT GREAT
THANK YOU
Thanks!
omg i wash watching this like, hmmmm this looks a lot like my chem lab room at UOIT...... duuuurrrr
thanks!!!
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
she is so sexy
