Each of the following reactions shows a solute dissolved in water. classify each solute as a strong electrolyte, a weak electrolyte, or a nonelectrolyte. a(l)→a(aq) bc(aq)⇌ b+(aq)+c−(aq) de(aq)→d+(aq)+e−(aq) xy(s)→x+(aq)+y−(aq) z(s)→z(aq)

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)  

As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.

(b)    

As partial dissociation of ions take place in this reaction as the reaction is in equilibrium state. Hence, it is a weak electrolyte.

(c)  

Here, complete dissociation of ions is taking place as the reaction is not in an equilibrium state. Therefore, it is a strong electrolyte.

(d)  

Here also complete dissociation is taking place. Hence, it is a strong electrolyte.

(e)  

As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.

the answer is d.) potassium
