This is the chemical transformation of sodium (Na) into different sodium compounds:

Sodium metal (Na) reacts with oxygen (O) to form sodium oxide (Na2O).Sodium oxide (Na2O) reacts with hydrochloric acid (HCl) to form sodium chloride (NaCl).Sodium chloride (NaCl) reacts with sodium hydroxide (NaOH) to form sodium hypochlorite (NaOCl).Sodium hypochlorite (NaOCl) reacts with phosphoric acid (H3PO4) to form sodium phosphate (Na3PO4).
