Abstract
Electrode potentials and electrical resistances of palladium wires alloyed with 5, 10, 20 and 25 per cent platinum have been measured while they absorbed hydrogen (dissolved under a pressure of 1 atm.) from aqueous solutions of 2 N sulphuric acid. Apparatus and techniques were similar to those previously employed1. The wires were 0.027 cm. in diameter and were prepared by directly alloying the metals. The measurements reported were made on 15-cm. lengths of wire in the cold-drawn condition, which were preactivated by discharging oxygen at their surfaces by electrolysis2,3. Potentials differing from zero were positive with respect to a platinum hydrogen electrode in the same solution.
