JEE Advanced 2016 Chemistry question
In neutral or faintly alkaline solution, 8 moles of permanganate anion quantitatively oxidize thiosulphate anions to produce **X** moles of a sulphur containing product. The magnitude of **X** is
Answer: 6
Solution
In neutral or faintly alkaline medium is reduced to (gain of 3 electrons) and thiosulphate is oxidised to sulphate (each S goes from average to , i.e. 8 electrons per
