Introduction to Mixtures
A mixture is a material composed of two or more substances that are physically combined, but not chemically combined. The substances in a mixture retain their own chemical properties and do not form a new substance. For example, salt (sodium chloride) is a mixture of sodium and chlorine. When salt is dissolved in water, the sodium and chlorine atoms remain separate.
What are Homogeneous Mixtures?
A homogeneous mixture is a substance in which the elements are evenly distributed throughout the sample. This means that you cannot see or feel any differences in the composition of the sample. A good example of a homogeneous mixture is water, which is composed of hydrogen and oxygen atoms that are evenly distributed throughout the sample.
Classification of homogeneous mixtures
A homogeneous mixture is a substance that is uniform in composition and properties throughout its mass. There are several different types of homogeneous mixtures, which are classified by the type of particles that make them up.
Solutions are homogeneous mixtures of two or more substances that are dissolved in a solvent. Solutions are typically named after the solvent, with the word “solution” added to the end. For example, a solution of salt in water is called a saline solution.
Colloids are homogeneous mixtures of two or more substances that are not dissolved in each other, but are instead dispersed evenly throughout the mixture. Colloids are typically named after the dispersed substance, with the word “colloid” added to the end. For example, a mixture of milk and water is a colloid.
suspensions are homogeneous mixtures of two or more substances that are not dissolved in each other, but are instead dispersed evenly throughout the mixture. Suspensions are typically named after the dispersed substance, with the word “suspension” added to the end. For example, a mixture of sand and water is a suspension.
