Anion analysis
POSTLABORATORY ASSIGNMENT 1. An iodide/chloride/sulfate unknown solution gave a yellow precipitate with AgNO The supernate did not react with Ba(NO)). The yellow precipitate did not dissolve in NH, H,O. After centrifuging the supernate was acidified with HNO, and gave a white precipitate. State the ion(s) present in the unknown solution. An iodide/chloride/sulfate unknown solution plus AgNO, gave no reaction. The solution was treated with Ba(NOs)2 and produced a white precipitate. State the ion(s) present in the unknown solution....
