When strong electrolytes completely ionize with water,they are not in equilibrium with the dissociated H+ ions.Only weak electrolytes are in equilibrium with their partly dissociated ions.Is this true/false...?(please be specific)

Expert Answer:

Yes it is true. Strong electrolytes are substances which ionise almost completely so the reactions for these electrolytes are written with a single headed arrow and not with a double headed arrow; they are not in equilibrium with the dissociated H+ ions. Whereas weak electrolytes are substances which ionise partially i.e to a small extent hence they are in equilibrium with the undissociated ions and the reactions are written with a double headed arrow.
