Bipolar electrochemistry concept. Bipolar electrochemistry is a phenomenon in electrochemistry based on the polarization of conducting objects in electric fields.Indeed, this polarization generates a potential difference between the two extremities of the substrate that is equal to the electric field value multiplied by the size of the object.
Commonly known as magic blue, it is the hexachloroantimonate salt of an amine radical cation. It is a blue solid that reacts with many solvents but is soluble in acetonitrile . The compound is a popular oxidizing agent in organic and organometallic chemistry , with a reduction potential of 0.67 V versus ferrocene /ferrocenium ( acetonitrile ...
The very term "acrocyanosis" is often applied inappropriately in cases when blue discoloration of the hands, feet, or parts of the face is noted. [1] The principal (primary) form of acrocyanosis is that of a benign cosmetic condition, [ 2 ] sometimes caused by a relatively benign neurohormonal disorder. [ 3 ]
The electrodes were reversibly and repeatedly oxidized and reduced by switching the polarity of an applied 1 V potential. This was observed by a color change between dark (reduced PEDOT) and light (oxidized PEDOT) blue within the electrodes, demonstrating the transport of ions between and into the electrodes. [1]
where and are activities of HCl solutions of right and left hand electrodes, respectively, and is the transport number of Cl −. Liquid junction potential is the difference between the two EMFs of the two concentration cells, with and without ionic transport:
Chronoamperometry is typically carried out in unstirred solution and at the fixed electrode, i.e., under experimental conditions avoiding convection as the mass transfer to the electrode. On the other hand, voltammetry is a subclass of amperometry, in which the current is measured by varying the potential applied to the electrode.
