Electrometric study on Cu(II), Hg(II) and Ag(I) complexes of isopropylmercaptan and determination of their solubility products

The complexation of copper (Cu +2), mercury (Hg +2) and silver (Ag +) ion with isopropylmercaptan has been studied in 25% (V/V) ethanolic media employing potentiometric, conductometric and amperometric titration techniques. Copper and mercury ions form 1:2 complex while silver ion shows the formatio...

Description
Summary:The complexation of copper (Cu +2), mercury (Hg +2) and silver (Ag +) ion with isopropylmercaptan has been studied in 25% (V/V) ethanolic media employing potentiometric, conductometric and amperometric titration techniques. Copper and mercury ions form 1:2 complex while silver ion shows the formation of 1:1 complex. Equilibrium constants and solubility products of these complexes have been evaluated by Ringbom's method at 10°, 20° and 30°C. The overall changes in thermodynamic functions Δ G, Δ H and Δ S accompanying complexation have also been determined at 20°C with the help of an isobar and Gibb's Helmholz equation.
