Precipitate Lab My unknown chemical is sodium iodide. This was determined by testing the chemical with cations such as silver nitrate, cobalt (II) nitrate, and copper nitrate. It was also tested with anions: sodium iodide, sodium carbonate, sodium oxalate, and sodium phosphate. It was tested to see if the product will yield a precipitate or solid (cloudiness, power, or crystals) and any color changes that are very similar to the products/changes when all the known cations and anions were tested for changes. First of all, sodium iodide is an anion, it was determined that the unknown chemical was an anion because it did not react with any of the anions. Since the unknown did not react with the anions, it did not produce a solid or precipitate. This is chemically true because the new products will both contain NO3, or nitrate, and NO3 is aqueous with all cations. When the unknown...
