A dietitian includes one of the following mixtures in the lunch menu. Classify each as homogeneous or heterogeneous. b. tea

Verified step by step guidance

1. insert step 1> Identify the components of tea. Tea typically consists of water, tea leaves, and possibly other ingredients like sugar or lemon.
2. insert step 2> Consider how these components are distributed in the mixture. In a well-prepared tea, the components are uniformly distributed.
3. insert step 3> Determine if the mixture has a uniform composition throughout. If the tea is properly mixed, it should appear the same throughout, indicating a uniform composition.
4. insert step 4> Classify the mixture based on its uniformity. A mixture with a uniform composition throughout is classified as homogeneous.
5. insert step 5> Conclude that tea, when properly prepared and mixed, is a homogeneous mixture.

Key Concepts

Homogeneous Mixtures

Homogeneous mixtures are uniform in composition and appearance, meaning that the individual components are not distinguishable. An example is a solution where the solute is completely dissolved in the solvent, such as saltwater. In these mixtures, any sample taken will have the same composition throughout.

Heterogeneous Mixtures

Heterogeneous mixtures consist of visibly different substances or phases. The components can often be separated by physical means, and their proportions can vary throughout the mixture. Examples include salad or a mixture of sand and gravel, where the individual components remain distinct.

Classification of Mixtures

The classification of mixtures into homogeneous and heterogeneous is essential in chemistry and food science. This classification helps in understanding the properties and behaviors of different mixtures. For instance, tea, when brewed, is typically considered a homogeneous mixture because the tea leaves are not visible, and the flavor is evenly distributed throughout the liquid.
