Solutions can be separated using simple filtration.
The solute is present in a smaller amount than the solvent.
The concentration of a solution can only be expressed in terms of mass per cent.
A solution is a heterogeneous mixture.

Answer 1

The Correct answer is The solute is present in a smaller amount than the solvent.

Key Points

A solution is a homogeneous mixture of two or more substances.
In a solution, the substance in the smaller amount is called the solute and the substance in the larger amount is called the solvent.
The solute dissolves in the solvent to form a solution.
For example, in a saltwater solution, salt is the solute and water is the solvent.
It is possible to have solutions where the solute is present in a very small amount compared to the solvent, such as in dilute solutions.

Additional Information

Simple Filtration
- Simple filtration is a method used to separate an insoluble solid from a liquid.
- Solutions cannot be separated by simple filtration because the solute is completely dissolved in the solvent.
Concentration of a Solution
- The concentration of a solution can be expressed in various ways, such as mass per cent, molarity, molality, and normality.
Heterogeneous Mixture
- A heterogeneous mixture consists of substances that are not evenly distributed and have distinct phases.
- A solution is a homogeneous mixture, meaning the solute is uniformly distributed within the solvent.
