effect on the differential capacitance curve. In NaC104 electrolytes our results 12 agree substantially with Leikis eta/. 6'v that a capacitance minimum at -0.7 V occurs with dilute solutions. In concentrated (,-~ 1 M) electrolytes, capacitance curves for NaC104 and NaOH are similar, no minimum at
The reduction of cobalt(I1) at the dme has been studied in water and aqueous mixtures of formamide, dimethylformamide and acetonitrile. In water the study was carried out in various complexing and noncomplexing supporting electrolytes. The kinetic parameters have been calculated by Koutecky's method
The polarographic reduction of uranyl ion in nitric acid solution are found to be one electron reduction mechanism at lower acid concentration (0.1 M HNO,) and two electron mechanism at high acid concentration (2 M HNO,). Methanol shifted the half wave potentials to more negative values and increase
