MODULE 5 – CHEMISTRY OF SOLUTIONS (Part 1)
Retrieved from https://www.thoughtco.com/definition-of-aqueous-solution-604370
Desired Learning Outcomes:
At the end of this module, you should be able to:
1. define solution;
2. describe various types of solutions;
3. explain the factors affecting solubility;
4. calculate the concentrations of solutions using various concentration units;
5. perform dilution calculations for solutions;
6. define the colligative properties and perform calculations involving the colligative
properties.
Solutions are abundantly present in the environment. Seawater, rain, vinegar, salt solution, alloys, and
amalgam are examples of solutions. A solution is a homogeneous mixture made up of two or more
substances with each substance retaining its own physical and chemical properties. A solution has a uniform
composition. There are two components in a solution, solvent, and solute. The solvent is the component in
large amounts and the solute is the component in a small amount. The solvent is the dissolving medium and
the solute is the substance to be dissolved. In the chemistry laboratory, distilled water is commonly used as
the solvent in the preparation of solutions. Water is known as a universal solvent because it can dissolve
many different substances, especially those that are hydrophilic (water-loving) in nature. A solution with water
as a solvent is called an aqueous (aq) solution.
Types of Solutions
Many of us are familiar with liquid solutions with a liquid as the solvent. Other types of homogeneous mixtures
can be classified as solid solutions and gas solutions. The physical state of the solution depends mostly on
the physical state of the solvent because it constitutes the major part of the solution. Table 1 shows the
different types of solutions with their examples.
