Explanation:
A substance that completely dissociates into ions when dissolved in its aqueous solution is known as a strong electrolyte.
Whereas a substance that does not dissociate into ions is known as a non-electrolyte.
If a substance partially dissociates into ions when dissolved in its aqueous solution then it is known as a weak electrolyte.
(a) [tex]A(l) \rightarrow A(aq)[/tex]
As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.
(b) [tex]BC(aq) \rightleftharpoons B^{+}(aq) + C^{-}(aq)[/tex]
As partial dissociation of ions take place in this reaction as the reaction is in equilibrium state. Hence, it is a weak electrolyte.
(c) [tex]DE(aq) \rightarrow D^{+}(aq) + E^{-}(aq)[/tex]
Here, complete dissociation of ions is taking place as the reaction is not in an equilibrium state. Therefore, it is a strong electrolyte.
(d) [tex]XY(s) \rightarrow X^{+}(aq)+Y^{-}(aq)[/tex]
Here also complete dissociation is taking place. Hence, it is a strong electrolyte.
(e) [tex]Z(s) \rightarrow Z(aq)[/tex]
As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.
