In the thermal transformation, several substances function as catalysts e.g., iodine, sodium, and sulfur. Black phosphorus appears to consist of four different forms. These are obtained by the application of heat and pressure to the white form. The major uses of elemental phosphorus involve the production of phosphoric acid and other chemicals.

Chat OnlineChlorine in its elemental state is a halogen gas Cl2, which is highly toxic and corrosive. Because of safety concerns with chlorine gas, many food processing facilities have changed to either sodium hypochlorite or calcium hypochlorite for water treatment. Chlorine gas and sodium hypochlorite can be produced in an electrochemical process.
Chat OnlineDrop the piece of sodium into the water. Immediately stand back. As water dissociates into H and OH-, hydrogen gas will be evolved. The increasing concentration of OH-ions in the solution will raise its pH and cause the liquid to turn pink. After the sodium has reacted completely, you can flush it with water and rinse it down the drain.
