Organic acid complexation influence on stannous ions electrochemical behaviour

Introduction The competitive complexation of Sn(II) hydroxycomplexes and Sn(II) complexes with organic acids present in fruit juices, has been studied, in a first stage, by the experimental method of titration. This method allows to compare the complexing power of different organic acids. Applied to tartaric and acetic acids it shows that tartaric acid is more complexing towards tin than acetic acid.
