Chapter 20, Problem 31E

Interpretation Introduction

Interpretation: The number of moles of $\text{AgI}$ that precipitate out is to be calculated when ${\text{AgNO}}_{\text{3}}$ is added to each complex compound $\text{Co}{\left({\text{NH}}_{\text{3}}\right)}_{\text{6}}{\text{I}}_{\text{3}},\text{Pt}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}{\text{I}}_{\text{4}},{\text{Na}}_{\text{2}}{\text{PtI}}_{\text{6}}$ and $\text{Cr}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}{\text{I}}_{\text{3}}$ in separate beakers.

Concept introduction: The formation of solid in a solution is known as precipitation.
