$a$ and $y$ respectively are


$a$ and $y$ respectively are
  1. $8 ; 3$
  2. $8 ; 6$
  3. $3 ; 6$
  4. $8 ; 8$

Solution

$8 \mathrm{MnO}_4^{-}+3 \mathrm{~S}_2 \mathrm{O}_3^{2-}+\mathrm{H}_2 \mathrm{O} \longrightarrow$ $8 \mathrm{MnO}_2+6 \mathrm{SO}_4^{2-}+2 \mathrm{OH}^{-}$ From the reaction it is clear that, $a=8$ and $y=6$.
