415Physical Properties of Negative Half-Cell Electrolytes
Except for the curve at 15°C, the change in the corrected conductivity of
the solutions follows the wave shape. A slight drop in the conductivity is
initially observed at concentrations below 0.8 M, which is followed by an
increase in the conductance to a maximum around 1.3 M. Similar behaviour
was reported for a number of ternary systems MX–HX–H
2
O, where MX is
the salt and HX is the acid. Zinc sulphate–sulphuric acid–water mixture in
particular was reported to show similar curves when the concentration of
the salt was increased at constant acid concentration. The measured conduc-
tivity values were correlated to the concentration of different species in the
solution. The calculation ...
