Visit Product Comparison Guide Description General description Potassium thiocyanate is an inorganic potassium salt. WebThe volhard method is a procedure for titrating silver (I) with standard potassium thiocyanate (KSCN). The titration is carried out in acidic solution. When the silver (I) has been precipitated as white silver thiocyanate, the first excess of titrant and the iron (III) indicator react and form a soluble red complex.
