Quizplus · Accepted Answer

An anion is a negatively charged ion, and HCO₃⁻ (bicarbonate) fits this description. Additionally, it is a compound because it contains more than one element (hydrogen, carbon, and oxygen). The other options include Na⁺ (sodium cation), Cl⁻ (chloride anion), K⁺ (potassium cation), and NaCl (sodium chloride), but they are either cations or simple compounds consisting of only two elements.
