Question

A mixture of sand and salt is a __________ (homogeneous/heterogeneous) mixture.

Answer 1

• A mixture is formed when atoms or molecules of the same or different substances combine with each other physically.
• For example - Air is a mixture of gases like Carbon dioxide, Nitrogen, Oxygen, etc; dust, Water vapors.
• Mixtures are of two types - Homogeneous and Heterogeneous.
• A mixture whose components can be seen from naked eyes is called a homogeneous mixture, while whose components cannot be seen from naked eyes are called heterogeneous mixtures.
• Since, in a mixture of sand and salt, both can be seen distinctly. Hence, it is a heterogeneous mixture.

A mixture of sand and salt is a heterogeneous mixture.
