Identify some beverages that are mixtures. Classify them as solutions, suspensions, or neither. Explain your classifications.
Minchanka [31]

Answer:

See explanation.

Explanation:

Hello.

In this case we can for instance take into account the following mixtures:

- Orange juice.

- Tea.

- A soda.

- Salty water

- Coffee.

Thus, since the orange juice is a suspension as long as it contains different sizes of orange pulp particles that cannot be dissolved mostly because of its organic nature.

Tea can be a solution when we place a tea bag in a cup with warm water since just soluble components of tea are successfully dissolved in the water. Moreover, homemade tea based on some plants are fruits may behave as a suspension due to the oraginic particles that are not dissolved in the water yet suspended.

A soda is a solution of some water-soluble compounds, gaseous soluble carbon dioxide and water which are homogeneously distributed in the solution.

Salty water can be a solution if you put some salt in warm or just cold water and wait until it dissolves completely.

Coffee can be also a solution or suspension depending on how it is made, which type of coffee is used and the amount of coffee added to the hot water.

Best regards.
