Text Solution

Verified by Experts

The correct Answer is:
C
Calchie is crude salt-peter `(NaNO_3)` and contains about 0.3% of `I_2` as `NaIO_3`. After the recovery of `NaNO_3` by crystallisation, the mother liquor containing `NaIO_3` is treated with `NaHSO_3` when `I_2` is set free
`15NaHSO_3 + 6NaIO_3 to 3I_2 + 6Na_2SO_4 + 3H_2O + 9NaHSO_4`
