β¦ Synopsis
The conductance of dilute solutions ofTlN0, at 20,25,30,35 and 40Β°C in DMSO was measured, and the polarographic behaviour of the above solution at 25Β°C was studied. The experimental results of conductivity measurements were analysed using the LesWheaton equation. The dependence of diffusion coefficient of thalious ions on the total ionic strength of solutions 1s also investigated. where N is the Avogadro's number, e, the electron 7. G.
