Chapter 20, Problem 33QAP

Interpretation Introduction

Interpretation:

The concentration of Pb+2 at equilibrium, should be calculated under given conditions.

Concept introduction:

K_sp is solubility product constant which is generally obtained as an equilibrium constant for solubility equilibrium of such solutions which are slightly soluble.

It is expressed as the product of ionic concentration of each ion raised to the power of its co-efficient. The expression is given as:

$\begin{array}{c}\text{For any reaction;S(s)}\to {\text{aP}}^{\text{+m}}{\text{(aq)+bQ}}^{\text{-n}}\text{(aq)}\\ {\text{K}}_{\text{sp}}{\text{=[P}}^{\text{+m}}{\text{]}}^{\text{a}}{{\text{[Q}}^{\text{-n}}}^{\text{]}}\end{array}$
