\(a\) and \(y\) respectively are
- A \(8 ; 3\)
- B \(8 ; 6\)
- C \(3 ; 6\)
- D \(8 ; 8\)
Answer & Solution
Correct Answer
(B) \(8 ; 6\)
Step-by-step Solution
Detailed explanation
\(8 \mathrm{MnO}_4^{-}+3 \mathrm{~S}_2 \mathrm{O}_3^{2-}+\mathrm{H}_2 \mathrm{O} \longrightarrow\)
\(8 \mathrm{MnO}_2+6 \mathrm{SO}_4^{2-}+2 \mathrm{OH}^{-}\)
From the reaction it is clear that, \(a=8\) and \(y=6\).
\(8 \mathrm{MnO}_2+6 \mathrm{SO}_4^{2-}+2 \mathrm{OH}^{-}\)
From the reaction it is clear that, \(a=8\) and \(y=6\).
