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

Conc. Of `NaIO_3` after mixing
`=0.002/2`=0.001 M
Conc. Of `Cu(Cl O_3)_2` after mixing
`=0.002/2=0.001` M
`NaIO_3 hArr Na^(+) +IO_3^-`
`[IO_3^-]`=0.001 M
`Cu(ClO_3)_2 hArr Cu^(2+) + 2ClO_3^-`
`[Cu^(2+)]` =0.001 M
Ionic product of `Cu(IO_3)_2`
`=[Cu^(2+)][IO_3^-]^2`
`=(0.001)xx(0.001)^2`
`=1xx10^(-9)`
Since ionic product is less than `K_(sp)(7.4xx10^(-4))` , no precipitation will occur.
