Which substance is a pure compound?

a. Gold

b. Water

c. Milk

d. Fruit cake

Expert Solution & Answer

Interpretation Introduction

Interpretation: From the given substances, a pure compound is to be identified.

Concept Introduction: Pure substances are of two types - elements and compounds. A compound is made up of two or more elements that are combined in a fixed proportion.

Answer to Problem 1SAQ

Correct answer: Water is a pure compound.

Therefore, option (b) is correct.

Explanation of Solution

Reason for correct option:

A compound is a substance that is made up of two or more elements in fixed definite proportions. In comparison to pure elements, compounds are more common. This is so because elements, being chemically reactive, undergo combinations with other elements, resulting in the formation of compounds.

Water is a pure compound. It is made up of hydrogen and oxygen in a definite proportion. It can be decomposed into simpler substances.

Hence, option (b) is correct.

Reasons for incorrect options:

Option (a) is gold, which is an element. So, it is an incorrect answer.

Option (c) is milk, which is a complex mixture. It consists of water, sugar, and fats. So, it is an incorrect answer.

Option (d) is fruit cake, which is a mixture of different compounds. So, it is an incorrect answer.

Hence, options (a), (c), and (d) are incorrect.
