Question

In mildly alkaline medium, thiosulphate ion is oxidized by $Mn{O}_4^{-}$ to $A$ . The oxidation state of sulphur in $A$ is________.

Answer 1

Answer: 6

$S_2{O}_3^{2-}+Mn{O}_4^{-}{\to }_{}^{AlkalineMedium}S{O}_4^{2-}+Mn{O}_2$
$A\to S{O}_4^{-2}$
$\therefore$ Oxidation no. of ${}^{\prime }{S}^{\prime }=+6$ Ans.
