摘要：

Heats of transport for dilute aqueous HCl solutions at 25 degrees C have been determined from the measurements of thermoelectric powers of the thermocell (T) Ag-AgCl vertical bar HCl(aq.)vertical bar Ag-AgCl (T + Delta T) The variation of the heat of transport with concentration has been examined up to 0.04 M and the molar heat of transport at infinite dilution obtained by extrapolation. Present experimental results may be summarized by the equation Q* = 3397 - 3734I(1/2) + 33610I(3/2) where Q* is the heat of transport in cal-mole(-1) and I is the ionic strength.
