A mixture of sodium salts may enclose one or more of the anions studied in this experiment. All of the salts are readily as well as completely soluble in cold water. While silver nitrate is added to the solution, a precipitate forms. Explain what anions are shown to be conclusively present in the unknown solution? Explain what anions are shown to be the definitely absent? For which anions are the test inadequate to confirm their presence or absence? Anions cl-,I-,SO42-,CO32-,NO3-,PO42-
