organic chem lab - wash technique
« on: November 15, 2010, 07:30:31 PM »
what's the purpose of performing 2 or 3 washes of 10mL each instead of one wash of 20 or 30mL?

I assume you are talking about solvent extraction? Look up partition co-efficients

You wash, let dry.  Wash, let dry.  Wash, let dry.

Rather than Wash, let dry.
