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)

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

(2)

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

(3)

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

(4)

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

(5)

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