Chapter 15, Problem 15.107SP

Interpretation Introduction

Interpretation:

The fraction of uncomplexed ${\text{Cr}}^{\text{3+}}$ ion present in the solution prepared by the dissolution of $\text{5}\text{.0}\times {\text{10}}^{-3}{\text{ mol Cr(OH)}}_3$ in $\text{1}\text{.0 L of 1}\text{.0 M NaOH}$ has to be calculated

Concept Introduction:

Equilibrium constant: At equilibrium the ratio of products to reactants (each raised to the power corresponding to its stoichiometric coefficient) has a constant value, K

For a general reaction, $\text{aA+bB}\rightleftarrows \text{cC+dD}$

$\text{Equilibrium}\text{constant}\text{K}\text{=}\frac{{\left[\text{C}\right]}^{\text{c}}{\left[\text{D}\right]}^{\text{d}}}{{\left[\text{A}\right]}^{\text{a}}{\left[\text{B}\right]}^{\text{b}}}$
