Answer :
Strong electrolyte substance are, (A) and (D)
Weak electrolyte substance is, (C)
Non-electrolyte substance is, (B)
Explanation :
Strong electrolyte : It is defined as the species that can completely dissociates into ions in its aqueous solution.
Weak electrolyte : It is defined as the species that is partially dissociates into ions in its aqueous solution.
Non-electrolyte : It is defined as the species that does not dissociates into ions in its aqueous solution.
As we are given the following reactions. Now we have to determine the solute as a strong electrolyte, a weak electrolyte, or a non-electrolyte.
(A) [tex]Ba(NO_3)_2(aq)\rightarrow Ba^{2+}(aq)+2NO_3^-(aq)[/tex]
This compound is an ionic which contains metal cation and non-metal anion. The complete dissociation into ions and only onside arrow represent the completely dissociated. So, it is a strong electrolyte.
(B) Ne
This is a monoatomic atom that has no charge that means, there is no dissociation into ions. So, it is a non-electrolyte.
(C) [tex]NH_3[/tex]
This is a molecular compound which do not contain metal cation and not an acid because it does not contain ionizable hydrogen atom. It is a base and it is a weak-electrolyte.
(D) [tex]NaOH(aq)\rightarrow Na^{+}(aq)+OH^-(aq)[/tex]
This compound is an ionic which contains metal cation and non-metal anion. The complete dissociation into ions and only onside arrow represent the completely dissociated. So, it is a strong electrolyte.
