Keywords: arsenic trioxide; potassium bromate; redox titration.
The method chosen here to assay the potassium bromate is the redox titration of bromate with arsenious oxide in acid medium (8,9,10), because of the availability of the primary standard, SRM 83d, Arsenic Trioxide Redu ctometric Standard, and the simplicity of the reaction.
Specific techniques are then covered, with an introductory chapter to each family of techniques-- including acid/base & redox titrations, electrochemistry, spectrometry/spectroscopy, chromatography, and kinetics --and then specific procedural and mathematical guidance.
We have started to investigate possible replacements for this chemical in some uses in undergraduate labs involving redox titrations.
TL Easy, available from Gerhardt UK, is an accurate, self-contained programmable titration unit which is suitable for pH and redox titrations, for both sugars and salts the redox mode is used.
