Abstract

The stability constant of substituted 2pyrazole (P1) with Cu(II), Co(II), Ni(II), Mn(II) complexes using pH metric titration technique in 90% DMF-water mixture at an ionic strength of 0.1M KNO3 were studied. The data obtained showed that Cu (II) has highest stability while Mn(II) has lowest stability.
