Each of the following reactions shows a solute dissolved in water. Classify each solute as a strong electrolyte, a weak electrolyte, or a nonelectrolyte?
M(l)→M(aq)
AC(aq)⇌A+(aq)+C−(aq)
BD(s)→B+(aq)+D−(aq)
PR(aq)→P+(aq)+R−(aq)
N(s)→N(aq)

Answer :

Strong electrolyte solutes are BD and PR.

Weak electrolyte solute is AC.

Non-electrolyte solutes are M and N.

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.

(1) [tex]M(l)\rightarrow M(aq)[/tex]

In this reaction, there is no dissociation into ions. So, It is a non-electrolyte.

(2) [tex]AC(aq)\rightleftharpoons A^+(aq)+C^-(aq)[/tex]

In this reaction, the partial dissociation into ions and equilibrium arrow represent the incomplete dissociation. So, it is a weak electrolyte.

(3) [tex]PR(s)\rightarrow P^+(aq)+R^-(aq)[/tex]

In this reaction, the complete dissociation into ions and only onside arrow represent the completely dissociated. So, it is a strong electrolyte.

(4) [tex]BD(aq)\rightarrow B^+(aq)+D^-(aq)[/tex]

In this reaction, the complete dissociation into ions and only onside arrow represent the completely dissociated. So, it is a strong electrolyte.

(5) [tex]N(s)\rightarrow N(aq)[/tex]

In this reaction, there is no dissociation into ions. So, It is a non-electrolyte.
