You are given a colorless unknown solution that contains one salt from the following set: NaX, NaY, NaZ. In solution, each salt dissociates completely into the Na+ ion and the anion Xā, Yā, or Zā, whose properties are given in question 1. The Na+ ion is inert. Assuming you have access to solutions of X, Y, and Z, write a simple procedure (in the form of a flowchart) for determining the identity of the salt that is present in your unknown.
