Polarographic behaviour of thionates

Proceedings of the Indian Academy of Sciences - Section A Aims and scope Submit manuscript

Summary

  1. 1.

    The polarographic behaviour of the thionates has been studied employing potassium iodide, potassium chloride, hydrochloric acid, and various buffers as electrolytes in the base solutions. The effect of incorporating 50% alcohol in the base solution has also been investigated.

  2. 2.

    The results indicate that the reduction process is essentially an irreversible process with tri- and tetrathionates while the opposite effect is noticed with pentathionate.

  3. 3.

    The tetrathionate shows the phenomenon of split wave which is practically absent in trithionate solutions.

  4. 4.

    A method has been suggested for the estimation of thionates in a mixture based on the use of 50% alcohol in the base solutions.

  5. 5.

    The mechanism of the reduction process has been discussed.
