Which formula represents a salt?

Explanation:
Salts are ionic compounds formed from a metal cation and a nonmetal anion, typically produced when an acid and a base react. Potassium chloride fits this idea because it is made of potassium ions (K+) and chloride ions (Cl−) in an ionic lattice. It’s a classic salt formed from neutralization of a base with an acid. The other formulas are not salts: CH3OH is a covalent alcohol molecule; CH3COOH is a molecular acid with an acidic hydrogen; KOH is a strong base. So KCl is the salt.
