Which formula represents a salt?
A. KOH.
B. KCl.
C. CH3OH.
D. CH3COOH.
CH3COOH is an organic acid, acetic acid also called ethanoic acid. Choice A will yield the OH- ion in solution (this compound is therefore a base). Choice C is an alcohol. Salts are ionic compounds that do not form OH- or H+ ions. KCl forms K+ and Cl- ions. Therefore it is a salt.
