Chapter 8, Problem 8.1EP

Interpretation Introduction

Interpretation:

The statements about the general properties of solutions are true or false has to be identified.

Concept introduction:

Solution: It is the homogeneous mixture of two or more substances. In such a mixture, solute is a substance (of lower proportion) dissolved in another substance (of larger proportion), called solvent. In aqueous solution, the solvent is water.

Homogeneous mixture:

• It is a mixture in which the components are uniformly distributed throughout the mixture.
• There is only one phase of matter observed in a homogeneous matter.
• Example- Air, Sugar water , Rain water

Explanation of Solution

Reason for true statements:

Option a):

In a solution, more than one substance can dissolve in a given solvent.

Hence, the statement is true.

Option b):

A solution is formed by dissolving two or more substances in a solvent. In a solution, the components are distributed uniformly through-out and hence it is homogeneous.

Hence, it is true.

Option c):

In a solution, the components are distributed uniformly throughout and thus every part is exactly the same.

Hence, it is true.

Reason for wrong statements:

Option d):

A solution is a homogenous mixture and it does not separate into parts. Therefore, the solutes present in a solution will not settle out with time if kept undisturbed.

Hence, the statement is wrong.
