A chemical test needs to be determined whether a white solid salt is Na 2 SO 4 or Na 2 S 2 O 3 with chemical equations. Concept introduction: When Na 2 SO 4 is warmed with dilute HCl, no visible reaction takes place. When Na 2 S 2 O 3 is warmed with dilute HCl, the solution turned slightly cloudy as yellow sulfur is formed. The solution becomes denser when warm. When Na 2 SO 4 is add to silver nitrate solution no reaction at first, then a faint white precipitate appeared due to the formation of silver sulfate ( Ag 2 SO 4 ) . A white precipitate is obtained when Na 2 S 2 O 3 is add to silver nitrate solution. The precipitate is dissolved on shaking. When more AgNO 3 is added, the remaining precipitate turns yellow.
