Electrolytic conductivity of mixed electrolyte solutions has been stud
ied theoretically and experimentally on the basis of recent phenomenol
ogical theories of conductivity. For 1:1 electrolytes a generalised mi
xture rule is deduced, applicable to mixtures of any number of ionic s
pecies. For mixtures of dissimilar electrolytes the simple mixture rul
e does not apply. However, for mixtures of 1:1 electrolytes with elect
rolytes of other charge type (2:2, 2:1 electrolytes), when the 1:1 ele
ctrolyte is present in marginal quantities, a modified additivity rule
is established. In this case the 1:1 electrolyte can be used to probe
the properties of the dominant electrolyte in the solution.
