Abstract
Transference numbers of HCl(aq) solutions at 25°C, from 0.01 to 13.6 mol-kg−1(m) have been obtained by measuring the emf of cells with transference using hydrogen gas/platinum electrodes. Good agreement is obtained at concentrations up to 1 m with all previous data, and our results strongly corroborate those of King and Spiro over the 2–8m concentration range. The transference numbers of the hydronium ion fit the empirical equation, HCl H = 0.821 + 0.0457m 1/2 − 2.476×10−2m − 1.90×10−4 m 2 − 1.45×10−5 m 3 the maximum deviation in T HCl H being 0.003.
