Question

Identify the solutions among the following mixtures.
I) Soil
II) Sea water
III) Coal
IV) Soda water

Answer 1

• Soil- It is a heterogeneous mixture containing various components. Therefore, it is not a solution.
• Sea water- It is a homogeneous mixture of common salt and water (considering clean sea water). Since the components are not visible to the naked eyes, sea water is a solution.
• Coal- It is a heterogeneous mixture containing various components. Therefore, it is not a solution.
• Soda water- It is a homogeneous mixture of carbon dioxide and water. Since the components are not visible to the naked eyes, soda water is a solution.
