style="background-color:rgb(250, 250, 250); color:rgb(17, 17, 17); font-family:arial,verdana,helvetica,sans-serif; font-size:11.2px">Potentiometric studies have been carried out on complexes of gabapentin (chemically 2-[1-(aminomethyl)cyclohexyl]ethanoic acid ) with Cu(II), Cd(II), Co(II), Ni(II), Pb(II) and Zn(II) in 50% v/v dioxane-water medium at three different temperatures (35, 45and 55o style="background-color:rgb(250, 250, 250); color:rgb(17, 17, 17); font-family:arial,verdana,helvetica,sans-serif; font-size:11.2px">C) and ionic strength 0.1 mol L-1 style="background-color:rgb(250, 250, 250); color:rgb(17, 17, 17); font-family:arial,verdana,helvetica,sans-serif; font-size:11.2px"> (KNO3 style="background-color:rgb(250, 250, 250); color:rgb(17, 17, 17); font-family:arial,verdana,helvetica,sans-serif; font-size:11.2px">). Calvin-Bjerrum pH titration technique as used by Irving and Rossotti has been applied to determine stability constants of the complexes. Free energy, enthalpy and entropy changes have also been evaluated.
