A mixture of sodium salts may contain one or more of the anions(Cl-, I-, SO42-, NO32-,PO43-) . All of the salts are readily andcompletely soluble in cold water. Two samples of this aqueoussolution show no precipitate when AgNO3 orBaCl2 is added. What anions are shown to be conclusively present in the unknown solution? Which anions are shown to bedefinitely absent? For which anions are the tests insufficient toconfirm their presence or absence. Explain your logic for eachstep.
