Silica gel in iodine jar for tlc
« on: December 19, 2014, 12:47:55 AM »
Why do we need silica gel in the iodine jar to develop a tlc?  My guess is that it has to do something with absorbing?!

You don't need the silica, but the plate will develop faster with the silica in there.

Hint: Surface area
