If a solution containing 0.10 M Cl-, Br-, I-, and LaTeX: CrO_4^2-C r O 4 2 − is treated with Ag+, in what order will the anions
Musya8 [376]

Answer:

AgI \longrightarrow AgBr \longrightarrow Ag_2CrO_4 \longrightarrow AgCl

Explanation:

The first thing to have in mind is that the Ksp (constant of solubility) gives you an idea of how much soluble a salt is.  <u>If the concentration of ions of that salt exceeds the kps, the salt will precipitate</u>.

The Kps of all these salts are very small compared to the 0.1 M concentration of the anions so all of them will precipitate.

The smaller the constant, the faster the salt precipitates

Having that concept in mind, the order of precipitation from first to last would be:

AgI \longrightarrow AgBr \longrightarrow Ag_2CrO_4 \longrightarrow AgCl
