lectrochemical reduction reaction in the course of the titration of Eu ( 2.2.2)and Eu( 2.2)using strong bonding solvent,DMSO,in C_2H_4Cl_2 has been investigated by cyclicvoltammetry. The greater the concen tration of strong bonding solvent,the more negative the half-wave potentials for the reduction reaction are. The coordination number of Eu(2.2.2 ) and Eu(2.2)which are 2 and 3 respectively,with DMSO can be calculated,according to the relations betweenhalf -wave potentials and the variety of concentration of DMSO.
