100%
A student performing his lab experiment receives her Unknown solution and begins to conduct tests to identify the anions present. The acidification with nitric acid generates bubbles. The addition of aqueous barium nitrate to the remaining solution yields no precipitate. The addition of aqueous silver nitrate forms a precipitate. This precipitate is then basified with 6M aqueous ammonia and the precipitate completely dissolves. The resulting solution is re-acidified with nitric acid and a white precipitate forms. Which anions were present in the student’s unknown? Explain.
