Chapter 1, Problem 1.9QP

Classify each of the following as a pure substance, a homogeneous mixture, or a heterogeneous mixture: (a) seawater, (b) helium gas, (c) salt, (d) diet cola, (e) a milkshake, (f) bottled water, (g) concrete, (h) 24K gold, (i) liquid nitrogen.

Interpretation Introduction

Interpretation:

The classification should be drawn for the following substance, a homogeneous mixture or heterogeneous or pure substance.

Concept Introduction:

Heterogeneous and homogeneous mixture:

A homogeneous mixture is a mixture in which the components are uniformly distributed throughout the mixture.

Means the composition of the mixture is same thought the mixture.

There is only one phase of matter observed in a homogeneous mixture.

So we can observe only one state of matter.

Like only solid or liquid or gaseous in a homogeneous mixture.

Homogeneous mixture example:

• Air
• Sugar water
• Rain water
• Vodka
• Vinegar
• Dishwashing detergent
• Steel

A heterogeneous mixture is a mixture in which the compound of the mixture is not uniformly mixed with different properties.

Different sample present in the mixture are not identical to each other& also present in different properties.

There are always two or more phases in a heterogeneous mixture.

Heterogeneous mixture example:

• Cereal in milk
• Vegetable soup
• Pizza
• Blood
• Gravel
• Ice in soda
• Salad dressing
• Mixed nuts
• Bowl of colour candies
• Soil

Pure substance:

It is defined as the substance that is made of only one type of atoms or molecule.

The measure of substance is pure is termed as purity.

The temperature at which the pure substance melt ,known as melting points of that pure substance.

The temperature at which the pure substance boil, known as boiling points of that pure substance.

Explanation of Solution

The seawater is a heterogeneous mixture and biological matter, but biomass filtered the sea water to homogeneous mixture.

One phase of matter observed in a homogeneous mixture.

Because, the components are uniformly distributed throughout the mixture.

A homogeneous mixture is a mixture in which the components are uniformly distributed throughout the mixture.

Means the composition of the mixture is same thought the mixture.

There is only one phase of matter observed in a homogeneous matter.

So we can observe only one state of matter.

Like only solid or liquid or gaseous in a homogeneous mixture.

Homogeneous mixture example:

• Air
• Sugar water
• Rain water
• Vodka
• Vinegar
• Dishwashing detergent
• Steel

It is defined as the substance that is made of only one type of atoms or molecule.

The measure of substance is pure is termed as purity.

The temperature at which the pure substance melt ,known as melting points of that pure substance.

The temperature at which the pure substance boil, known as boiling points of that pure substance.

Explanation of Solution

The helium gas is a pure substance and highly stable in nature.

This is inert in nature and occupied stable configuration.

It does not take part any chemical reaction due to unavailability of electron in outer most shell.

Due to the above factor, it’s consider as pure substance

Pure substance:
