Question

Quizplus · Accepted Answer

HCO₃⁻ is an anion (negatively charged ion) and a compound (it consists of multiple atoms bonded together, specifically one hydrogen atom, one carbon atom, and three oxygen atoms). The other choices are either cations (positively charged ions) or simple ions (consisting of only one type of atom). NaCl is a compound, but it is not an anion (it is made up of both a cation, Na⁺, and an anion, Cl⁻).
