Chapter 4.7, Problem 15PE

Interpretation Introduction

Interpretation: The validation of the statement that all the lead will be removed from $15.00\text{mL}$ of $7.52\times {10}^{-3}\text{M}$ $\text{Pb}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ on addition of $12.50\text{mL}$ of $0.0115\text{M}$ ${\text{Na}}_{\text{2}}\text{S}$ is to be stated.

Concept introduction: The concentration of a solution is defined as the number of moles of solute dissolved in a liter of solution. Concentration of a solution is expressed in moles per unit volume of a substance.

To determine: If all the lead will be removed from $15.00\text{mL}$ of $7.52\times {10}^{-3}\text{M}$ $\text{Pb}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ on addition of $12.50\text{mL}$ of $0.0115\text{M}$ ${\text{Na}}_{\text{2}}\text{S}$.
