Electroanalytical investigations on formation of thallium(I) molybdates as a function of pH
The formation of thallium(I) molybdates obtained by interaction of thallium(I) nitrate and sodium molybdate at specific pH levels 7.6, 5.5 and 4.1 has been studied by electrometric techniques involving potentiometric and conductometric titrations, in aqueous and alcoholic media using each reagent as...
