Question

sand will dissolve in water true or false​

Answer 1

Answer:

False

Explanation:

Soil is heavier than water, i.e. its density is more than that of water. When we mix sand and water , no reaction takes place . The sand simply settles down at the bottom of the water container. This is because sand is heavier than water and hence cannot float in water.

Answer 2

This is a false statement. Sand will not dissolve in water because-

• The sand is heavier than the water. When we put sand in a beaker containing water, it will not dissolve but settles at the bottom of the water. This is called a heterogeneous mixture in which components of the mixture are visible through the naked eye and are not evenly distributed throughout the mixture.
• As components are visible, we can separate the sand from water by physical methods such as filtration.

Note: If a substance dissolves in water, it forms a homogeneous solution in which components of the solution cannot be seen through the naked eye.
