The great attraction of PET is its versatility, its relative affordability, lack of shattering and its ability to be recycled. Correct answers: 2 question: PLEASE ANSWER QUICKLY sulfur is soluble in the flammable liquid xylene but not in water. The sulfur will be left in the filter as the residue and the sodium nitrate and water will become a solution because it is soluble in water and it will become the filtrate in the flask. Any water content will reduce the solubility of S 8 while increasing temperature increases the solubility. This smell can be detected in air concentrations as low as one part per million (PPM)! Sulfur (S) Sulfur, particularly in its S8 form, is insoluble in water but dissolves in carbon disulfide, anhydrous liquid ammonia and methylene iodide.
