Abstract

RS- ion is called as thiolate anion and it is well stated in the literature that certain metals made complexes with thiolate anion, in order to prove this fact a study was design to check the affect of different concentrations of lithium carbonate on the status of thiolate anion by using UV-visible spectrophotometer. Results show that there is decrease in the concentration of thiolate anion with the increase in concentration of lithium ions showing the possibility of interaction between lithium ion and thiolate anion resulting in the formation of oligomeric Li-S-R.
