N2  - The application of chronopotentiometry as an electroanalytical technique for the in situ determination of silver(1) in molten KNO3-Ba(NO3)2 (87.6 : 12.4 mole%) eutectic has been described. Reduction of silver(1) on platinum microelectrode is found to be a reversible, single-step one-electron process. Diffusion coefficients, D (cm2 s-l), of silver(1) in the melt have been determined and its temperature variation in the range 578-697 K could be expressed by the relation (R = 8.314 J K-1 mol-1):     D = 0.913 x 10-3 exp(-19810/RT)  Effect of the presence of the divalent Ba2+ cations in the fluid on the diffusion process has been discussed.
