Question

In neutral or faintly alkaline solution, 8 moles of permaganate anion quantitative oxidize thiosulphate anions to produce X moles of a sulphur containing product. The magnitude of X is :

Answer 1

$8Mn{O}_4^{-}+3S_2{O}_3^{-2}+H_{2}O\to 8Mn{O}_2+6S{O}_4^{-2}+2O{H}^{-}$

$\therefore$ Mole of $S{O}_4^{2-}$ formed from 8 moles of $Mn{O}_4^{-}=6$
