Drying an Organic Solution
additional sodium sulfate doesn't clump up – the mixture is now said to be "free flowing". Procedure: • When you are ready to dry a solution, pour it into a clean beaker (flasks don't work as well). Start by checking to make sure that there are no visible water droplets or a water layer on the bottom or top of the solvent.
