x millimole of KlO(3) react completely w...

x millimole of `KlO_(3)` react completely with y millimole of KI to give `I_(2)` quantitatively. It z millimole of hypo are required for complete titration against the `I_(2)` product, then

A

`z=6x`

B

`6y=5z`

C

`5x=y`

D

`x+y=2x`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`KIO_(3)+KIrarrI_(2)`
m eq `KIO_(3)` = m eq KI = m eq `I_(2)`
`x xx5=yxx1=nxx(5)/(3)`
`I_(2)+Na_(2)S_(2)O_(3)rarrNa_(2)S_(4)O_(6)+NaI`
m eq `I_(2)` = m eq `Na_(2)S_(2)O_(3)`
`x xx2=zxx1`
`implies x=(z)/(2)implies5x=y=(5z)/(6)`.

Iodine titration can be iodemotire or iodimetric depending on using iodine directly or indirectly as an oxidising agent in the redox titration. a) Iodimetric titration in which a standard iodine solution is used as an oxidant and iodine is directly or indirectly titrated against a reducing agent. For example 2CuSO_(4)+4KIrarrCu_(2)I_(2)+2K_(2)SO_(4)+I_(2) b) Iodimetric procedures are used for the determination of strength of reducing agent such as thiosulphates, sulphites, arsenties and stannous chloride etc., by titrating them against standard solution of iodine in a burette. 2Na_(2)S_(2)O_(3)rarr2NaI+Na_(2)S_(4)O_(6) Starch is used as indicator near the end point which form blue colour complex with I_(3)^(-) .
