good job man!!
Sometimes a visual just helps you so much to prepare for lab. Thanks for
the upload.
wow, shows what a simple animation can do….great video 😀
@JGalz my nigga. word
Okay I’m 4 months late, but here’s the answer: For a solute to dissolve in
a solvent, the interactions between solute molecules and those of solvent
are similar to those between the solvent molecules themselves. For example,
Iodine has VDW(Van der Waal’s) between it’s molecules so it dissolves in
hexane that also has VDW. But Iodine does not dissolve in water, as water
has hydrogen bonding. Similarly, Ammonia dissolves well due to extensive
hydrogen bonding between NH3 and H2O molecules.
if u consider TLC which has stationary phase like silica gel or alumina
then both are polar, so they cn form bonds like H-bonds with polar
molecules then they will be adsorbed more strongly and so will not move
with the solvent.Eg-consider o-nitrophenol and p-nitrophenol, then
o-nitrophenol is above than para bcz para cn form H-bonds with silica but
ortho already has intermolecular H-bond,, thats why adsorbed less strongly
nd so rises up with the mobile phase
great animation, but there are still some issues that aren’t clear to me –
how can polar molecules have more afinity with the stationary phase, which
is also polar? how does this atraction between molecules with equal
polarity work? weren’t polar substances suposed to atrack non-polar
substances? i’m getting trouble understanding this, any kind of help would
be really appreciated!
the solvent moves up the paper because of capillar action?
