Introduction: The purpose of this lab was to use qualitative analysis, or the testing of a substance or mixture to determine its chemical constituents, to identify the anions and cations of 14 unknown solutions. Identification was achieved by observing such things as physical appearance, appearance under a flame, pH levels, and reactions with other solutions. Qualitative analysis, as opposed to quantitative analysis, works only to determine the components of a mixture and does not regard t...
