Question

$S{O}_3^{2-}+S^{\ast }\stackrel{boil}{\to }S{S}^{\ast }{O}_3^{2-},$
$S{S}^{\ast }{O}_3^{2-}+2H^{+}\to H_{2}S{O}_3+S^{\ast }$
The above reaction sequence proves:

• A. Two sulphur atoms of thiosulphate are not equivalent
• B. Both are equivalent
• C. Both of the above are correct
• D. None of these

Answer 1

Answer: (A)

Two sulphur atoms of thiosulphate are not equivalent

As every time $S^{\ast }$ is forming at the end of reaction so it proves that
two sulphur atoms of thiosulphate are not equivalent.
