Equal volumes of 0.002 M solution of sodium iodate and cupric chlorate are mixed togather. Will it lead to precipitation of copper iodate?
`("for cupric iodate" K =7.4xx10^(-8))`.

Explanation

`underset(0.002xxV)(2NaIO_(4))+underset(0.002xxV)(Cu(CIO_(4))_(2))rarr underset(("Let V mL of each mixed"))(Cu(IO_(4))_(2)+2NaCIO_(4)`
`underset("mixing")(Meq.on)`
For `Cu(IO_(4))_(2):`
`q=[Cu^(2+)][IO_(4)^(-)]^(2)`
`Q=[(0.002xxV)/(2V)][(0.002xxV)/(2V)]^(2)`
`=10^(-9)`
The numerical value of `Q(10^(-9))` is lesser than `K_(SP)` of `Cu(IO_(4))_(2)` and thus no precipitation.
