Difference between double salt and complex with example.
A coordination compound contains a central metal atom or ion surrounded by number of oppositely charged ions or neutral molecules. These ions or molecules re bonded to the metal atom or ion by a coordinate bond.
A double salt is formed when two salts in stoichiometric ratio are crystallised together from their saturated solution.
Coordination compoundsdo not dissociate into simple ions when dissolved in water whereas double salts do.
Coordination compounds :K4[Fe(CN)6]
Double salt :FeSO4.(NH4)2SO4.6H2O (Mohrs salt)
Double salt dissociates into its simpler ions completely when dissolved in water whereas compex do not.
As KCl.MgCl2.6H2O being a double salt dissociates inyo K+, Mg+2, etc
Whereas [Fe(CN)6] being complex complex don't show the presence of all its constituent particles.
