WebAnother is that analysis of anions usually relies on spot tests of the anions rather than separations followed by Confirmatory tests. For these reasons, the study of qualitative analysis often begins with the anions. The common anions you will test for are carbonate, phosphate, sulfate, bromide, chloride, iodide, acetate, thiocyanate, and nitrate. http://alpha.chem.umb.edu/chemistry/ch117/117%20labs/Lab%206%20Qualit%20anion%20analysis%20sum%202411.pdf
