Barium Analysis by Automated Photometric Titration
10 Dec 2015Because of its high chemical reactivity barium is never found in nature as a free element. Barium can be determined in alkaline media by direct titration with EDTA. Phthalein purple is used as indicator; the equivalence point is determined with the Optrode at a wavelength of 574 nm.
