Electrolytes
Chemrcal substances which can ccnduct electricity in their aqueous stare or tn molten state are called electrolytes. The conduction of current through electrolyte is due to the movement of ions.
1. Strong Electrolytes
Electrolytes which dissociate almost completely into constituent ions in aqueous solution are known as strong electrolytes. e.g.. all salts (except HgCl2, CdBr2)’ mineral acids like HCl, H2)SO4, HNO3 etc.. and bases like NaOH. KOH. etc.
2. Weak Electrolytes
Electrolytes which dissociate to a lesser extent in aqueous solution are called weak electrolyte. All organic acids (except sulphonic acids), and bases like NH3. NH4OH, amines etc.
Degree of Ionisation or Degree of Dissociation (α)
It is the fraction of the total number of molecules which ionise (dissociate)into constituent ions.
α = (number of molecules ionised or dissociated/total number of molecules taken)
For strong electrolytes,
α = 1
For weak electrolytes
α < 1
Values of the degree of dissociation (ex)depends upon the following factors
nature of solutenature of solventconcentrationtemperature
