When a mixture of water, sand, and salt is filtered, what passes throughthe filter paper? (1) water, only(2) water and sand, only(3) water and salt, only(4) water, sand, and salt

Option (3) is the correct answer.

Explanation:

A mixture is defined as the substance that contains two or more different number of substances that are physically mixed together.

For example, a mixture of iron nails, sand and water.

A mixture in which solute particles are unevenly distributed into the solvent then it is known as a heterogeneous mixture.

For example, salt and sand in water is a heterogeneous mixture.

A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed in a solvent.

A homogeneous mixture is a clear solution.  

So, when a mixture of water, sand, and salt is filtered then sand will remain in the filter paper but salt being soluble in water will pass through the filter along with water.

Hence, slat water we will get.

Thus, we can conclude that when a mixture of water, sand, and salt is filtered, then water and salt, only passes through the filter paper.
