Abstract
Electrochemical behavior of 1.0mM bis(2,2'-bipyridyl)copper( II )(<TEX>${Cu(bpy)_2}^{2+}$</TEX>) in 100mM NaCl+27mM <TEX>$MgCl_2$</TEX> solution with and without sodium dodecyl sulfate(SDS) is investigated. In the presence of SDS, <TEX>$E_{pa}$</TEX> and <TEX>$E_{1/2}$</TEX> of <TEX>${Cu(bpy)_2}^{2+/1+}$</TEX> shifts to the positive direction compared to the SDS free. Teh intersection of two lines on <TEX>${\Delta}E_p$</TEX> vs. -log[SDS] plot for 1.0mM <TEX>$Cu(bpy)_2(NO_3)_2$</TEX> in 100mM NaCl+27mM <TEX>$MgCl_2$</TEX> solution is a critical micelle concentration(CMC). Reduced form <TEX>${Cu(bpy)_2}^{1+}$</TEX> in the presence of <TEX>$MgCl_2$</TEX> is more easily associated to dodecyl sulfate anion(<TEX>$DS^-$</TEX>) than oxidized <TEX>${Cu(bpy)_2}^{2+}$</TEX>. As the ionic strength is increased by the addition of multiply charged cations(<TEX>$MgCl_2$</TEX>), the double layer becomes more compact and micelle formation is more difficult.
