Electrical conductance measurements of [<I>x</I>NaSCN+(1−<I>x</I>)KSCN]+<I>R</I>H<SUB>2</SUB>O system were made as functions of <I>x</I> and <I>R</I> at 25 °C. The mixed alkali effect was found to be negligible when <I>R</I>>10 and it increased sharply with increase in concentration in the range <I>R≤</I>10. The concentration dependence of molar conductance (<I>Λ</I>) has been described satisfactorily by the expression, <I>Λ</I>=<I>Λ</I><SUB>FH</SUB>exp (<I>Bm</I>+<I>Cm</I><SUP>2</SUP>) where <I>Λ</I><SUB>FH</SUB> is the Falkenhagen–Leist–Kelbg equation for <I>Λ</I>, <I>m</I> is the molality and the parameters <I>B</I> and <I>C</I> are the empirical constants.
