What is the molecular state of sulphur as reactant in, sulphur `+12OH^(-) rarr 4S^(2-)+2S_(2)O_(3)^(2-)+3H_(2)O`?

A

`S_(8)^(2-)`

B

`2S_(4)^(3-)`

C

`S_(8)`

D

`S_(8)^(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
Let sulphur be as `(s_(n))^(x)`
`x=` charge
`n=` number of sulphur atoms
`(S_(n))^(x)+12OH^(-) rarr 4S^(-)+2S_(2)O_(3)^(2-)+3H_(2)O`
Charge-balanced: `x+(-12)= -8-4`
`:. X =0`
sulphur-balanced: `x=4+4`
`:. S=8`
Thus, `(S_(8))`.
