Product Code: RXSOL-62-6126-050

Categories: Test Kit For Water-62
Product Short Description: Potassium Thiocyanate solution also used to determine Chloride, Bromide and Iodide in presence of Silver Nitrate with Potassium Thiocyanate titrant using a Ferric Alum Indicator.
Product Description:

Potassium Thiocyanate solution can be used in titrations involving Silver Nitrate solutions. Chloride, Bromide and Iodide can be determined indirectly this way by adding excess Silver Nitrate solution to the sample containing the Halide, thus precipitating the Halide, and titrating the excess Silver Nitrate with Potassium Thiocyanate titrant using a Ferric Alum Indicator. 

Product Application:

The reactions for this Volhard titration are:

X- + excess AgNO3 → AgX (precipitate) + AgNO3
X = Cl, Br, I

KSCN + AgNO3 → AgSCN (white precipitate) + KNO3

excess SCN- + Fe3+ → [FeSCN]2+ (red complex at endpoint)

Product Dose:

Potassium Thiocyanate solution can also be used to standardize Mercuric Nitrate solutions using Ferric Alum as the indicator:

2 KSCN + Hg(NO3)2 → Hg(SCN)2 (white precipitate) + 2 KNO3

excess SCN- + Fe3+ → [FeSCN]2+ (red complex at endpoint)

Ammonium Thiocyanate and Potassium Thiocyanate solutions can be used interchangeably in these determinations.
