Chapter 10, Problem 11STP

Interpretation Introduction

Interpretation:

The number of possible compounds which can be made from copper, sulfur, and oxygen should be predicted. The charge and formula of some ions is represented as follows:

Concept introduction:

The species containing either positive or negative charge are termed as ions. Positively charged ions are termed as cations whereas negatively charged ions are termed as anions.

Answer to Problem 11STP

Five compounds are possible whose formula and name are given as follows:

S. No.	FORMULA	NAME OF THE COMPOUND
1.	${\text{Cu}}_{\text{2}}\text{S}$	Copper(I) sulfide
2.	$\text{CuS}$	Copper sulfide
3.	${\text{CuSO}}_3$	Copper sulfite
4.	${\text{CuSO}}_4$	Copper sulfate
5.	${\text{CuS}}_2{\text{O}}_3$	Copper thiosulfate

Explanation of Solution

The charge on copper can be +1 and +2. Thus, the possible compounds which can be made are represented as follows:

Thus, five compounds are possible using copper, sulfur, and oxygen atom.
