Answer 1

The reaction of sulphur in alkaline medium is given below:

\[\ce{S8(s) + {a} OH^-(aq) -> {b} S^{2-}{aq} + {c} S2O^{2-}3(aq) + {d} H2O{(l)}}\]

The values of 'a' are 12.

Explanation:

\[\ce{S8(s) + {a} OH^-(aq) -> {b} S^{2-} + {c} S2O^{2-}3 + {d} H2O}\]

The balanced chemical equation is

\[\ce{S8 + 12 OH^-(aq) -> 4 S^{2-} + 2 S2O^{2-}3 + 6 H2O}\]
