The reaction of sulphur in alkaline medium is given below: S 8 s + a OH aq − → b S aq 2 − + c S 2 O 3 aq 2 − + d H 2 O l The values of ' a ' is______ (Integer answer)

Correct answer

0

Step-by-step solution

For balancing in basic medium add equal number of OH ⊖ . That of H + 2   S 8 + 12 H 2 O + 24 OH ⊖ ⟶ 8   S 2 - + 4   S 2 O 8 2 - + 24 H 2 O 2   S 8 + 24 OH ⊖ → 8   S 2 - + 4   S 2 O 8 2 - + 12 H 2 O S 8 + 12 OH ⊖ → 4   S 2 - + 2   S 2 O 8 2 - + 6 H 2 O a = 12
