Journal of Chemical Education, v60 n12 p1071 Dec 1983 Describes a procedure for the qualitative analysis of aluminum subgroup cations designed to avoid failure to obtain lead or barium chromate precipitates or failure to report aluminum hydroxide when present (due to staining). Some lab tests provide qualitative results and others quantitative. A procedure called a Western blot, for example, typically provides only qualitative data -- whether or not a particular protein was present, but not how much of it was present. In other experiments or lab tests, quantitative data is preferable.
