Conductivities Λ for ZnSO4/MgSO4 + sucrose/trehalose + water systems were measured.
Values of Λ0 for ½ZnSO4 and ½MgSO4 decrease with increasing saccharide molality.
Values of Λ0 for ½ZnSO4 and ½MgSO4 at a given mS are in the order: sucrose > trehalose.
Values of Λ0 for ½ZnSO4 at given mS are larger than those for ½MgSO4.
