Chapter U4.84, Problem 7E

Interpretation Introduction

Interpretation: The list of three patterns in the given bases needs to be determine.

Concept Introduction: On the basis of taste, reactivity and presence of ions; substances can be classified as acidic and basic. An acidic substance can be defined as the substance that can give ${\text{H}}^{\text{+}}$ ions in the solution. A basic substance can give ${\text{OH}}^{\text{-}}$ ions in its solution.

Explanation of Solution

Given information:

• Sodium hydroxide − NaOH
• Magnesium hydroxide − ${\text{Mg(OH)}}_{\text{2}}$
• Potassium hydroxide − $\text{KOH}$
• Lithium hydroxide − $\text{LiOH}$
• Barium hydroxide − ${\text{Ba(OH)}}_{\text{2}}$
• Ammonium hydroxide − ${\text{NH}}_{\text{4}}\text{OH }$

In the given bases, the most common patterns are:

• The prefix in the name is the name of metal/cationic part.
• All the names of the bases are ended with −hydroxide.
• In the chemical formula, the common pattern is the presence of -OH in the chemical formula.
