Which substance is classified as a salt?

Explanation:
Salts are ionic compounds formed when an acid reacts with a base, producing a cation from the base and an anion from the acid. Calcium chloride fits this as it contains Ca2+ and Cl− ions, making it an ionic compound that dissociates in water to give those ions. The others aren’t salts: calcium hydroxide is a base (a hydroxide), ethanol is an alcohol, and carbon tetrachloride is a covalent molecule. Therefore, calcium chloride is the salt.
