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

Answer»

`Z=6x`
`6y=5z`
`5x=y`
`x+y=2x`

Solution :`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)`.
