Chapter 12, Problem 3ASA

You are given a colorless unknown solution that contains one of the following salts: $\text{NaA}$, $\text{NaB}$, $\text{NaC}$. In solution, each salt dissociates completely into the ${\text{Na}}^{\text{+}}$ ion and the anion ${\text{A}}^{-}$, ${\text{B}}^{-}$, or ${\text{C}}^{-}$, whose properties are given in Problem 2. The ${\text{Na}}^{\text{+}}$ ion is effectively inert. Given the availability of solutions of ${\text{A}}_{\text{2}}$, ${\text{B}}_{\text{2}}$, and ${\text{C}}_{\text{2}}$, develop a simple procedure for identifying the salt that is present in your unknown.
