An ionic compound made up of a cation from a base and an anion from an acid is a(n)

An ionic compound made up of a cation from a base and an anion from an acid is known as a salt.

Salts are formed during a neutralization reaction, where an acid reacts with a base. The cation comes from the base (which is typically a metal or ammonium ion) and the anion comes from the acid (which is typically a non-metal ion or polyatomic ion). For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the resulting salt is sodium chloride (NaCl), which is commonly known as table salt.

Salts consist of ionic bonds and can often crystallize into solid structures. They can vary widely in their properties, including solubility in water, which will depend on the specific cations and anions present.
