Chapter 15, Problem 80A

(a)

Interpretation Introduction

Interpretation: To determine the type of electrolyte.

Concept Introduction: An electrolyte is a substance that, when in contact with water, splits into charged ions. Positively charged ions can also be cations.

Answer to Problem 80A

Non-electrolyte

Explanation of Solution

A non-electrolyte is a solute that dissolves without dissociating, or separating, into ions. Therefore, solutions produced by the solvation of non-electrolytes will not include ions and are only made up of neutral molecules.

In the given pic, atoms of the molecules are not ionized; hence, it can be considered as a non-electrolyte.

(b)

Interpretation Introduction

Interpretation: To determine the type of electrolyte.

Concept Introduction: An electrolyte is a substance that, when in contact with water, splits into charged ions. Positively charged ions can also be cations.

Answer to Problem 80A

Weak-electrolyte

Explanation of Solution

A weak electrolyte is a solute that partially dissociates or separates throughout the solvation process through its component cations as well as anions.

In the given pic, it can be seen that atoms are partially ionized that’s why they can be considered weak electrolytes.

(c)

Interpretation Introduction

Interpretation: To determine the type of electrolyte.

Concept Introduction: An electrolyte is a substance that, when in contact with water, splits into charged ions. Positively charged ions can also be cations.

Answer to Problem 80A

Strong electrolyte

Explanation of Solution

An electrolyte that dissociates almost entirely in water is said to be a strong electrolyte. Hydrogen chloride would be a good illustration of a strong electrolyte (HCl).

In the given pic, atoms are ionized that’s why they can be considered strong electrolytes.
