Chapter 15, Problem 22QAP

Interpretation Introduction

Interpretation:

The K_sp for Ni(OH)₂ at given conditions should be determined.

Concept introduction:

A constant that defines the solubility equilibrium that exists between a compound in its solid state and its ions in the aqueous state is said to be solubility product constant. Its general expression is written as:

$\begin{array}{l}{\text{A}}_{\text{x}}{\text{B}}_{\text{y}}\text{(s)}\rightleftharpoons {\text{xA}}^{\text{+}}{\text{(aq) + yB}}^{\text{-}}\text{(aq)}\\ {\text{K}}_{\text{sp}}{\text{= [A}}^{\text{+}}{\text{]}}^{\text{x}}{{\text{[B}}^{\text{-}}}^{\text{]}}\end{array}$

Where K_sp is solubility product constant and square brackets represents concentration.
