Uvavanyo lweSodium Sulfide kwisisombululo se-iodine:
Faka i-25 mL yesisombululo se-iodine standard titration kwi-flask ye-iodine engama-250 mL. Yongeza i-25 mL yamanzi kunye ne-10 mL yesisombululo se-glacial acetic acid.
Ngelixa ujikeleza, yongeza nge-pipette iSolution B eyayine-titration ngaphambili (ukusuka kwinyathelo lesi-2). Titrate ngesisombululo se-titration esiqhelekileyo se-sodium thiosulfate de isisombululo sibe mthubi okhanyayo. Emva koko, yongeza i-2 mL yesisombululo se-starch indicator uze uqhubeke ne-titration de umbala oluhlaza okwesibhakabhaka uphele. Bhala phantsi umthamo osetyenzisiweyo njenge-V₂.Sodium Sulfide.
