Chapter 17, Problem 75E

Interpretation Introduction

Interpretation: The silver salts of the given anions present in the solution that precipitates out first from the solution is to be determined.

Concept introduction: The solubility product constant of a compound is the product of solubility of its ions raised to the power of their stoichiometric coefficients.

Depending on the different solubility product constant values of different silver salts with different concentrations, the anions precipitate out preferentially at different concentrations of silver ion.

To determine: The compound that precipitates out first when dilute ${\text{AgNO}}_{\text{3}}$ is added slowly to the solution containing $0.20\text{M}$

${\text{CrO}}_{\text{4}}{}^{2-}$ , $0.10\text{M}$

${\text{CO}}_{\text{3}}{}^{2-}$ and $0.010\text{M}$

${\text{Cl}}^{-}$ .
