Equal volumes of $AgNO X_{3}$ and $NaCl$ solutions are mixed. With $K_{s p} (AgCl) = 1.8 \times 1 0^{- 10}$ , in which cases does a precipitate form?

Mixing equal volumes halves each concentration. Ionic products are

2.5 \times 1 0^{- 11}

2.5 \times 1 0^{- 9}

1.0 \times 1 0^{- 10}

and

2.25 \times 1 0^{- 10}

respectively. Precipitation requires the product to exceed

1.8 \times 1 0^{- 10}

, which holds only for the second and fourth cases.
