Vedclass · Answer

(A) The structure of the thiosulfate ion $(S_2O_3^{2-})$ consists of a central sulfur atom bonded to three oxygen atoms and one terminal sulfur atom.In this structure,the central sulfur atom is in the $+6$ oxidation state,while the terminal sulfur atom is in the $-2$ oxidation state.When acidified,the thiosulfate ion undergoes disproportionation to form elemental sulfur $(S)$ and sulfur dioxide $(SO_2)$,making the acidic solution unstable.

An acidic solution of sodium thiosulfate is unstable because in thiosulfate,the two sulfur atoms have different oxidation states of:
