Colours again!

Can u explain in more understandable terms? Or atleast tell where this exten..... comes into this question or how it explains it, please.

Anyway in this case both are counter ions. So do they have any interactions wit the ligands in the coordination sphere?

@ mallika how can u apply hyperconjugation here

u hav now interested me in this topic

Any ideas, Vishal?

@mallika .. see d q....

all due 2 the unshared pair of e^-1 of both d counter ions

hey ANI can u giv som other example than K₄[Fe(CN)6) & Fe₂[Fe(CN)6]

if u cant then i will share my views (& i jst think u cant)

Yes. K₄[Fe(CN)₆] and Zn₂[Fe(CN)₆]

Wherever potassium ferrocyanate is used in qualitative analysis is an example

k.. tell me y color differs between

[Cr(H₂o)₄cl₂]cl.2H₂O

[Cr(H₂o)₅cl]cl₂H₂O

ONLY POTTASIUM FERROCYANATE????????

the reaction involves transfer of an electron when the metals differ and the co ord sphere is the same

@Ram: Constituents of Coordination sphere have changed. But in my q, they don't! And I know only of Potassium Ferrocyanate. There may be others.

and ani i think u r fooling others in Fe2[Fe(CN)6]

iron will exist as Fe⁴⁺ nt possible

so this compnd dont exist

k.. can u plz tell me whether in ur q d counter ions are ionisable????

ram i m nt getin u dude

i too ve never seen such a complex....

but seems to exist but not...........

@Vishal and Mallika: Doubt cleared?

It's what you get when you add K₄[Fe(CN)₆] to any solution with Fe²⁺ ions.
