Question

"A solution containing both barium nitrate and silver nitrate is added to a solution of the unknown sodium salts used in this exercise. What anion(s) will not produce a precipitate? What test could be used to confirm your answer? Explain your answers."

Answer 1

If the available salts are sodium carbonate decahydrate, sodium bromide, sodium chloride, sodium phosphate, sodium iodine, sodium nitrate, sodium nitrite, sodium sulfate decahydrate, and sodium sulfite, then ....

Ba²⁺(aq) will precipitate with carbonate (CO₃^2-), sulfate (SO₄^2-) so all the others would NOT produce a precipitate with barium nitrate.

Ag⁺(aq) will precipitate with CO₃^2-, bromide (Br^-), chloride (Cl^-), phosphate (PO₄^3-) and iodide (I^-)., so those that will NOT produce a precipitate would be silver nitrate and silver nitrite.
