The en$of the cell: Pd, H&)/HBr(m), x wt-y0 acetone-water mixture/AgBr,Ag was measured with x = 10, 30 and 50 at temperatures 15, 25 and 35Β°C in the molality range for HBr from 0.003 to 0.1 mol kg-l. From these data the standard potentials for AglAgBr electrode are obtained, and used in calculations
The emf of the cell Pt, HZ, HBz(m), Hg,Bz2, Hg in formamide has been measured at 5Β°C intervals over the temperature range 5-45"C. The values of the standard potentials of the mercurymercurous benzoate electrode can be fitted in the firm of equation, obtained by using the least squares method: E" = 0
