Chapter 17, Problem 66E

Interpretation Introduction

Interpretation:

The amount of the sparingly soluble salt and the volume of the solution is given. The concentration of the nickel ion in the given concentration of the solution of ammonia is to be determined.

Concept introduction: The formation constant of the complex, $K_{\text{f}}$ , is given by the formula,

$K_{\text{f}}=\frac{\left[{\left[\text{Ni}{\left({\text{NH}}_{\text{3}}\right)}_{\text{6}}\right]}^{2+}\right]}{\left[{\text{Ni}}^{2+}\right]{\left[{\text{NH}}_3\right]}^6}$

To determine: The concentration of the ammonia required to dissolve ${\text{NiC}}_{\text{2}}{\text{O}}_{\text{4}}$ .
