Cyclic Voltammetry for the Interaction between Bismuth Nitrate and Methyl Red in Potassium Nitrate Solutions
Journal Title: Chemical Methodologies - Year 2019, Vol 3, Issue 0
Abstract
Cyclic Voltammetry of bismuth nitrate (BN) using different concentrations was practically measured by the use of DY2000 potenstiostat. We used 0.1 M KNO3 as a transporting medium for the diffusion of the ions used as the glassy carbon electrode (GCE). Moreover, it was prepared in our laboratory, well polished and washed before use. Besides, Ag/AgCl reference electrode and auxiliary platinum electrode were also used. Scan rates of the redox reactions of bismuth nitrate were studied in the presence and absence of methyl red. The complexation interaction between bismuth nitrate (BN) and methyl red (MR) was studied. The redox reactions’ stability constant for forming complex and Gibbs free energy of complex interactions was evaluated. The data are discussed.
