Chapter 15, Problem 37QAP

Interpretation Introduction

Interpretation:

The precipitate formed needs to be determined, if a solution is made up by mixing $\text{125 ml of }0.\text{1}00{\text{ M AuNO}}_{\text{3}}$ and $\text{225 ml of }0.0{\text{49 M AgNO}}_{\text{3}}$ andafter that twenty-five mL of a $\text{0}\text{.0100M}$ solution of HCl is added to it.

Concept introduction:

To precipitate ${\text{Au}}^{\text{+}}$ and ${\text{Ag}}^{\text{+}}$ with ${\text{Cl}}^{-}$, the concentration of ${\text{Cl}}^{-}$ in the solution should be greater than the chloride ion concentration required to precipitate $\text{AuCl}$ and $\text{AgCl}$.
