Qualitative Analysis of Buffer Solutions

Qualitative Analysis II
Introduction:
In this experiment procedures were devised that enabled us to separate, properly identify mixtures of six different cations. After each cation is identified the procedures that were devised were used to identify which cations were present in an unknown solution. Qualitative analysis deals with the separation and identification of six cations: Ag+, Al3+, Ba2+, Ca2+, Fe3+, and Pb2+. Solubility equilibria, amphoterism, and complex-ion equilibria play important roles in the separation and identification of the unknown solution.
