Which of the following statements is true of the acid–base properties of common cations and anions in aqueous solutions? The anions that are conjugate bases of strong acids are strong bases. The acid-base behavior of anions of polyprotic acids is independent of the extent of deprotonation. Alkali metal and alkali earth cations have no measureable effect on solution pH. Basic anions are conjugate bases of acidic cations. Basic cations are conjugate bases of weak acids.
