Abstract: The polarographic behavior of Na₂S₂O₄ (I) in neutral and alk. medium is a good example of an electrode process where in the vicinity of the electrode there is reaction S₂O_4^2- → 20SO^2- (II) that is the decompn. of dimer into 2 monomers. The theoretical calcns. agree with the expts. and confirm the equil. of II in solns. It is also possible to calc. the relation of const. of decompn. of dimer 'k' and equil. const. K = [D]/[M]2. A reaction scheme, explaining the polarographic behavior of I in acid solns. and mechanism of the electrode processes of H₂SO₃, is given.
