Chapter 3, Problem 49E

Interpretation Introduction

Interpretation: The amount of nickel ion dissolved in ammonia 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 nickel ion in the given concentration of the solution of ammonia.
