You are given an unknown colorless, solution that may contain only on salt from the following set- NaA, NaB, NaC. In solution each salt dissociates completely into Na+ ion and the anion A-,B-, or C-, whose properties are A is green, B is yellow and C is red. The Na+ ion is effectively inert. Given the availability of solution of A, B, and C, develops a simple procedure for identifying the salt that is present in your unknown.
