GUYS,

How do you kno when the electrolyte is molten, aqeous or dilute.

EXAMPLE: JUNE'09 Q2.  :-[ :-[ :-[ :-[ :-[ :-[

Adham-amr:
if the electrolyte is molten it's used up e.g molten lead bromide Pb+ at cathode and Br- at anode
if aqueous or dilute they're both the same they have the same but extra two ions
e.g aqueous or dilute sodium chloride they have Na+ Cl- and H+ OH- from water
