what problem may occur if the disttalation pear shaped flask is filled to more than 90% full?
Homework Answers
If more than 90% of the flask is full, there are chances that all the vapours of different solvents may reach the condenser tube and get condensed. This will result in the impure solvent separation.
If you take mixture of solvents less than half or half of the bottle, the vapours formed from high boiling point solvent will have less chance to enter condenser tube at lower temperatures. It will condense and fall back to flask. Only the vapours of low boiling point will reach condenser and condenses to form liquid that can be collected.
