Polarographic studies of zinc with succinic, glutaric and adipic acids

Abstract

The succinate,  glutarate  and  adipate  complexes  of zinc  have  been examined  polarographically  and  their overall  stability  constants evaluated. Since  zinc is  reduced  quasi-reversibly  at  the dropping  mercury  electrode,  the  Gelling's  method  was used  to  obtain  the  reversible  half-wave  potential  (E 1/2)  from the observed  (Ek 1/2).The  standard rate  constant,  k,  was  of  the  order  of  10^-1  cm/s,  showing  a  quasi-reversible  reduction.
