3. A representation of one unit of KCl in water is shown below. (The water molecules are intentionally not shown.)

alukav5142 [94]

The representation is showing potassium atom (K) and Chlorine atom (Cl) when it ought to show their ions i.e potassium ion (K⁺) and Chlorine ion (Cl¯)

<h3>Dissociation equation for KCl</h3>

When potassium chloride, KCl dissolves in water, it dissociate to produce potassium ion (K⁺) and Chlorine ion (Cl¯) as shown below:

KCl(aq) —> K⁺(aq) + Cl¯(aq)

The representation given in the question is only showing potassium atom (K) and Chlorine atom (Cl). This makes it wrong as dissolution of ionic compounds in water will results in the corresponding ions of the element that makes up the compound
