✦ Synopsis

AbstractFrom a set of critically selected literary data on the e@s of concentration cells consisting of sodium metal and sodium amalgam in a sodium salt non-aqueous electrolyte a value of Eg+, bps+ = -1.955& V was calculated for the standard equilibrium potential of diluted liquid sodium am&am at 25°C. The standard state of the amalgam was derived from an amalgam at it&rite dilution where fNa -1.0 for x,.,*+ 0. The activity coefficient of sodium in the amalgam at an arbitrary composition, corresponding to this standard state, is obtained from the expression lg fN_wg, = 16.393 xNa.
