CAS No.: 7784-25-0

EINECS No.: 232-055-3

Use:
Used as an analytical reagent and as an indicator in the determination of halogens.
Ammonium ferric sulfate indicator method should be carried out in dilute nitric acid solution,
because iron ions can form ferric hydroxide precipitation in neutral or alkaline medium.
In order to prevent precipitation conversion (AgCl+SCN-→←AgSCN+Cl-), after ammonium ferric sulfate indicator method is prepitated with silver nitrate titrant, it should be added 5ml dibutyl phthalate
or 1 ~ 3ml nitrobenzene.
And the indicator liquid should be added after strong shaking,  then titrated with ammonium thiocyanate titration tiidine. Titration should be carried out at room temperature. At high temperature, red complex
fades easily.
