Spectrophotometric determination of the stability constants of 4-substituted thiosemicarbazides with Co2+ , Ni2+ and Cu2+ system

S B SAXENA, Y K AGARWAL

Abstract


Formation of 1: 2 complexes have been found out by the spectrophotometric studies. The apparent equilibrium constants are determined by general absorbance-extinction-concentration scheme and also by the method of Turner and Anderson at 31 (> C ± 1(> C and at constant ionic strength (0.0075 M).

Keywords


Thiosemicarbazide; chelate; stability; constant.
