Question

Classify each of the following mixtures as homogeneous of heterogeneous: a. vegetable soup b. sea water c. tea d. tea with ice and lemon slices e. fruit salad

Short answer

a. Heterogeneous, b. Homogeneous, c. Homogeneous, d. Heterogeneous, e. Heterogeneous

Step-by-step solution

- Understanding Types of Mixtures

Mixtures are classified into two types: homogeneous and heterogeneous. Homogeneous mixtures have a uniform composition throughout, while heterogeneous mixtures have a non-uniform composition.

- Classifying Vegetable Soup

Vegetable soup contains different ingredients like vegetables, broth, and possibly meat, which are visible and not uniformly mixed. Therefore, it is a heterogeneous mixture.

- Classifying Sea Water

Sea water is a solution where the salt is uniformly dissolved in water, resulting in a uniform composition. Thus, it is a homogeneous mixture.

- Classifying Tea

Tea, when the tea leaves or tea bag are removed, is a clear solution with uniform composition. Hence, it is a homogeneous mixture.

- Classifying Tea with Ice and Lemon Slices

Tea with ice and lemon slices contains solid ice and lemon slices that are distinct from the liquid tea, making the composition non-uniform. Therefore, it is a heterogeneous mixture.

- Classifying Fruit Salad

Fruit salad consists of various pieces of different fruits which are visibly distinct and not uniformly mixed. Thus, it is a heterogeneous mixture.

Key concepts

homogeneous mixtures

Homogeneous mixtures have the same composition and appearance throughout. They consist of one phase, meaning they look the same in every part. Examples are:

• citizen
• sugar in water
• steel (iron and carbon)

Homogeneous mixtures are also called solutions. You can't see individual particles, even under a microscope. The particles are evenly distributed, making the whole mixture look uniform.

heterogeneous mixtures

Heterogeneous mixtures are mixtures where you can see the different components. They do not have a uniform composition throughout. Examples include:

• vegetable soup
• fruit salad
• sand and iron filling mixture

In these types of mixtures, the substances do not blend smoothly and distinct layers or regions can be observed.

mixture classification

Classifying mixtures is essential in chemistry for understanding material properties. There are primarily two types of mixtures: homogeneous and heterogeneous.
Homogeneous Mixtures: These mixtures look the same throughout. Examples include sea water and tea without ice.
Heterogeneous Mixtures: These mixtures have visually different parts. Examples are vegetable soup, fruit salad, and tea with ice and lemon.
When classifying mixtures, focus on whether the composition is uniform or not.
