I am performing a conductivity test for my complex in different solvent and the product should be non electrolyte.
As for acetonitril and DMF the complex is non electrolyte but for DMSO the molar conductivity is nearly to electrolytic caracter, accroding to geary, it may be a weak electrolyte. is it normal to have diffenrent electrolytic caracters for the same product in different solvent and how do i explain it?
Dear friend Zerrouk Amina
Yes, the electrolytic nature of a metal complex can change from solvent to solvent. The reason for this is that the solvent molecules interact differently with the metal complex ions, affecting their ability to conduct electricity.
In general, polar solvents, such as DMSO, are better at solvating ions and can increase the mobility of the ions in solution, leading to higher conductivity. On the other hand, non-polar solvents, such as acetonitrile and DMF, are less effective at solvating ions and can hinder ion mobility, leading to lower conductivity.
The difference in electrolytic character of your metal complex in different solvents is likely due to the difference in solvent polarity and solvating power. In the case of DMSO, the solvent may be able to partially solvate the metal complex ions, leading to higher conductivity and a weak electrolyte character.
To explain this, you can discuss the solvent-solute interactions in each solvent, and how these interactions affect the ion mobility and conductivity. Additionally, you can compare the polarities and solvating powers of the different solvents to explain the differences in electrolytic character.
