the next 2 years.
When is a distillation in a closed system preferred over an open one? Does distilling nitric acid in a closed system not work because of the
production of nitrogen oxides generating too much pressure? |
My snarky reply is the exact thing you need!
If I understood you correctly, you have a degree? Or you've passed at least one chemistry subject? Nevermind. You want to know when is a distillation
in a closed system preferred over an open one? Always!
Dude, lack of experience with organic chemistry laboratory is not an excuse for not knowing this. This is basic laboratory knowledge. Laboratory
distillations with glass apparatuses are always made in an opened system. If the air/moisture needs to be kept out, the end of the system is closed
with a bubbler or a drying tube.
You obviously have no idea about the danger you were in. Hot, concentrated nitric acid in a pressurized system means "if possible, remove the source
of heat immediately and get the fuck out of the room".
If your Keck clips were stronger, or if the joints were more stuck, upon sudden releasing of the pressure your corrosive acid would've come out
shooting like a jet, similar to a shaked can of Coke. Have you seen the victims of nitric acid attacks in India? You better google it.
And learn to accept criticism, especially if the person criticizing you would hate to see you get hurt.
Next time you try to do something, take a peek into the lab manual. Forget fucking YouTube. |
