title: Investigation of manganese(III) fluoride for coulometric titration.
abstract: A study has been made of the use of electrogenerated manganese(III), in an electrolyte containing fluoride, for coulometric titration. The addition of fluoride prevented the deposition of manganese dioxide on the anode, and was responsible for increase of the current efficiency and for extension of the feasible range of current density, owing to complex formation between manganese(III) and fluoride. The bonding ratio, the apparent stability constant and the redox potential of the complex were also estimated from the Nernst equation and the current-potential curves.
