Chapter 16, Problem 16.149QP

(a)

Interpretation Introduction

To determine: The anion which will precipitate first in the given solution after the addition of lead (II) nitrate solution.

Interpretation: The anion which will precipitate first in the given solution after the addition of lead (II) nitrate solution is to be stated.

Concept introduction: The formation of insoluble solid product from the combination of anions and cations in aqueous solution is known as precipitation reaction.

The resulting solid product is known as the precipitate and the chemical substance due to which precipitation takes place is known as the precipitant.

(b)

Interpretation Introduction

To determine: The concentration of the first ion in the solution when the second ion starts to precipitate at $2\text{5}{}^{\text{ο}}\text{C}$.

Interpretation: The concentration of the first ion in the solution when the second ion starts to precipitate at $2\text{5}{}^{\text{ο}}\text{C}$ 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.
