1 " mol of "`IO_(3)^(ɵ)` ions is heated with excess of `I^(ɵ)` ions in the presence of acidic conditions as per the following equation
`IO_(3)^(ɵ)+I^(ɵ)toI_(2)`
How many moles of acidified bypo solution will be required to react completely with `I_(2)` thus produced?

A

1

B

3

C

5

D

6

Text Solution

Verified by Experts

The correct Answer is:
D
(i). `10e^(-)+2IO_(3)^(ɵ)toI_(2)`
`underline(2I^(ɵ)toI_(2)+2e^(-)]xx5)`
`underline(2IO_(3)^(ɵ)+10I^(ɵ)to6I_(2))`
(ii). `I_(2)+2S_(2)O_(3)^(2-)toS_(4)O_(6)^(2-)+2I^(ɵ)`
`1 " mol of "IO_(3)^(ɵ)=5 mol I^(ɵ)-=3 mol of`
`I_(2)=6 " mol of "S_(2)O_(3)^(2-)`
