Chapter 9.2, Problem 16SP

(a)

Interpretation Introduction

Interpretation: The name of the given ionic compound is to be stated.

Concept Introduction : Ionic compounds are formed by the transfer of electrons between metal and non-metal. They are named as $\text{Name}\text{of}\text{metal}+\text{Stem}\text{of}\text{non-metal}+\text{'}ide\text{'}$

Answer to Problem 16SP

The name of the compound is calcium oxalate.

Explanation of Solution

The given compound is ${\text{CaC}}_{\text{2}}{\text{O}}_{\text{4}}$ . It is composed of ${\text{Ca}}^{2+}$ (calcium ions) and ${\text{C}}_2{\text{O}}_4{}^{2-}$ (oxalate ions). Therefore, the name of the compound is calcium oxalate.

(b)

Interpretation Introduction

Interpretation: The name of the given ionic compound is to be stated.

Concept Introduction : Ionic compounds are formed by the transfer of electrons between metal and non-metal. They are named as $\text{Name}\text{of}\text{metal}+\text{Stem}\text{of}\text{non-metal}+\text{'}ide\text{'}$

Answer to Problem 16SP

The name of the compound is potassium hypochlorite.

Explanation of Solution

The given compound is $\text{KClO}$ . It is composed of ${\text{K}}^{+}$ (potassium ions) and ${\text{ClO}}^{-}$ (hypochlorite ions). Therefore, the name of the compound is potassium hypochlorite.

(c)

Interpretation Introduction
