Az eljárás közvetett módszer: a meghatározandó klorid oldatához fölös ezüst-nitrátot adunk és a felesleget ammónium-rodanid mérőoldattal vas(III)-só jelenlétében visszatitráljuk.

HCl + AgNO₃ = AgCl + HNO₃

AgNO₃ + NH₄SCN = AgSCN + NH₄NO₃

A meghatározás pontossága javul, ha az ezüstklorid csapadékot kiszűrjük, vagy forralással tömörítjük, majd 10%-os salétromsavval savanyítjuk a közeget. Indikátorként vas(III)ammónium-szulfátot használunk, ami gyengén vörösbarna színnel jelzi a végpontot.
