@rauc6788 Because if you need to shut the reaction down fast it's easier to drop the heating instead of raising the flask and the chance of spilling something is lower. Then again, usually you use a lifting platform and not clamps.
it's for safety purposes. if a reaction being heated gets out of control, you want to be able to lower the heat source which is much easier and safer than raising the flask. and so you have to leave enough room below the mantle. (this is what my lab prof said, ik im 11 years late)
any perticular reason two smaller buchner funnels are being used insted of one larger one. Had the same question about raising the mantle vs lowering the flask thanks bonham1981 your explanation makes sense
I noticed a white precipitate (salicylic acid) formed immediately after adding the HCL and of course I want to get maximum yield of salicylic acid during the lab. How do you know when all the precipitate has formed, when acidifying the solution with 6.0M HCL? I don't want to do Vacuum filtration too early and get a low yield.
