For precipitation the value of ionic product must be more than

K_{s p}

so that a super saturated solution is possible and precipitation occurs at once.
Here

1 0^{- 3} M A g \times 1 0^{- 3} MC l^{-} > K_{s p} (1 0^{- 12})

i.e. precipitation occurs maximum in it.

Q. When equal volume of the following solutions are mixed, which of the following gives maximum precipitate? ( $K_{s p}$ of $A g Cl = 1 0^{- 12}$ )

$1 0^{- 4} M A g^{+}$ and $1 0^{- 4} MC l^{-}$

$1 0^{- 3} M A g^{+}$ and $1 0^{- 3} MC l^{-}$

$1 0^{- 5} M A g^{+}$ and $1 0^{- 5} MC l^{-}$

$1 0^{- 6} M A g^{+}$ and $1 0^{- 6} MC l^{-}$
