Application Note: Tin Analysis using Automated Photometric Titration
28 July 2015
This application note describes the use of Metrohm’s Optrode Sensor for titration in the analysis of Tin. Tin forms very stable complexes with EDTA in its divalent and tetravalent form. In alkaline media, tin forms hydroxo complexes for which reason tin is titrated in acidic medium (pH 2.1). Xylenol orange is used as indicator; the equivalence point is detected with the Optrode at a wavelength of 574 nm.
