Chapter 16, Problem 16.121SP

Interpretation Introduction

Interpretation:

The molar solubility of $Cr{\left(OH\right)}_3$ in $$$0.5$$M$$NaOH$ must be found out.

Concept introduction:

Molar solubility of a salt is the maximum amount of salt in mole which can be dissolved in $1L$

• solution.
• Molar solubility decreases in presence of some common ion. This phenomenon is known as common ion effect.

Given:

Formation constant of $Cr{(OH)}_4{}^{-}=8\times {10}^{29}$
