In a 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:

Correct answer

6

Step-by-step solution

8 M n O 4 − + 3 S 2 O 3 2 − + H 2 O → 8 M n O 2 + 6 S O 4 2 − + 2 O H − Moles of S O 4 2 − formed from 8 moles of MSO 4 − = 6
