Dissociation of AlCl3
« on: September 15, 2012, 01:24:16 AM »
Can anyone please explain me the dissociation of AlCl3 in terms of alpha and 1- (alpha) that is by ostwalds dilution law?

THANKS

Very bad example. AlCl3 in water hardly hydrolyses instead of dissociation.
In non-protonizing solvents it forms complexes instead of dissociation. There a a few salts that in water, in fact, dissociate partially, eg: CdCl2 or HgCl2 but even then  the formation of complexes are impotrant part of problem

Technically Ostwald dilution law doesn't deal with multi step dissociation, so it can't be applied here.
