Chapter 4, Problem 70E

(a)

Interpretation Introduction

Interpretation: The solution that contain the higher concentration of iodide $\left({\text{I}}^{-}\right)$ ions among 0.10 M ${\text{BaI}}_{\text{2}}$ or 0.25 M $\text{KI}$ solution.

Concept introduction:

Salts are those that are completely dissociate into respective ions in the solution.
Concentration is the relative quantity of substance present in the solution or it is the ratio of constituent abundance to the volume of the solution.

(b)

Interpretation Introduction

Interpretation: The salt that contains higher concentration of iodide $\left({\text{I}}^{-}\right)$ ions among $100\text{mL}$ of $\text{0}\text{.10}\text{M}\text{KI}$ solution or 200 mL $\text{0}\text{.040}\text{M}$

${\text{ZnI}}_2$ of solution.

Concept introduction:

Salts are those that are completely dissociate into respective ions in the solution.
Concentration is the relative quantity of substance present in the solution or it is the ratio of constituent abundance to the volume of the solution.

(c)

Interpretation Introduction

Interpretation: The salt that contains concentration of iodide $\left({\text{I}}^{-}\right)$ ions among 3.2 M HI solution or a solution made by dissolving 145 g of $\text{NaI}$ in water to make 150 mL of solution.

Concept introduction:

Salts are those that are completely dissociate into respective ions in the solution.
Concentration is the relative quantity of substance present in the solution or it is the ratio of constituent abundance to the volume of the solution.
