Mixing liquids terms
« on: 15/06/2005 00:01:08 »

What is it called in chemistry when im mixing liquids?

 What is it called in Chemistry the sequence of putting the liquids a special order?

 If i change the sequence/order of putting in the liquids in the cup/jar what is this called in chemistry?

 What are some basic mixing techniques in chemistry?

 I know this is different mixing techniques i just need to know the terms or how to do these different mixing techniques?

I'm not sure these techniques have specific names to be honest. Mixing is mixing !

Nah... or at least I haven't come across particular terms... generally you'd say "mixed" or, if you're stirring it "stirred".
Usually, you'll see an experimental protocol which says something like "10ml of [chemical_x] was added to 15ml of [chemical_y] with stirring at -77C, the mixture was warmed to room temperature and heated under reflux for 3 hours. 5ml of [chemical_z] was added dropwise down the condenser over a period of 25 minutes." All it's doing is basically giving you a recepie.

You could mix some things just by pouring them together/ pouring one over another, but making sure they're well mixed tends to involve an electric stirrer... add a small bar magnet to your mixture, then stand it on a "hotplate stirrer" which has a larger magnet on a motor inside it and crank the speed up so the magnet in the pot spins with the magnet in the stirrer.

Or, if you are 007, it's shaken, not stirred !
