Sodium chloride serves as a prime example of a chloride because it consists of sodium (Na) and chlorine (Cl) ions bonded together in a 1:1 ratio. This compound is commonly known as table salt and is widely recognized for its role in cooking and food preservation. The presence of the chloride ion is fundamental in this compound, as it is directly formed by the reaction of sodium with chlorine.

In addition, sodium chloride's classification as a chloride is not just a matter of naming; it also relates to its chemical properties and behavior in solution. Chlorides generally exhibit solubility in water, and sodium chloride is highly soluble, contributing to its prevalent use in various industrial and culinary applications.

The other options involve compounds that do not contain the chloride ion. Sodium bicarbonate is a bicarbonate, potassium sulfate is a sulfate, and calcium carbonate is a carbonate. These compounds each have distinct chemical properties and structures that do not align with the characteristics of chlorides.
