Vorlacks wanted to know y in the world m i using balloons in the lab...
Having a party? with black balloons??
Yup...I bought black balloons...hehe...din know there r black balloons in the first place :P
Anyway, here's how they r used...
First the balloons are attached to syringes that have been partially cut-off...
Then they r filled with some inert gas...in my case...it's nitrogen...
After that a needle is attached to the syringe...and..
Used as shown below...hehe :D
On the left...balloon on a rubber stopper...waiting to be used...
On the right...balloon on a bottle of anhydrous solvent...so that I can draw the solvent out while N2 goes in ;)
In the middle...balloon on the condenser attached to my reaction flask...ensure it's dry and inert in the reaction flask...at the same time keeps the pressure pretty constant :D
