We explain what homogeneous mixtures are and what other types of mixture exist. Examples of homogeneous type mixtures.
What is a homogeneous mixture?
A homogeneous mixture is a union of two or more substances in which the original substances cannot be distinguished. The elements that make up the homogeneous mixture cannot be distinguished with the naked eye, but they are physically separable since there is no interaction between them. chemical reaction. For example: Tea with sugar or a mixture of water and alcohol.
The blends They are very commonly used and are used in aspects as diverse as cooking, construction, jewelry, among many others.
To achieve a mixture, it is enough to mechanically join two or more different substances until they form a joint matter. It is important to know that the components are mixed but retain their chemical properties and can usually be separated again through procedures such as sifted, the filtration, the magnetic separation, the decantation, the centrifugation, among others.
A mixture can be made with substances in liquid state, solid either gaseous. For example, alloys, which are homogeneous mixtures of metals. Another example of a homogeneous mixture is solutions wherein generally at least one component is a liquid. For example: salt dissolved in water.
Types of homogeneous mixture
The mixtures can be of two types:
- Homogeneous mixtures. They are those mixtures in which each of the components that compose it cannot be differentiated with the naked eye. They are also known as solutions. For example: Juice powder.
- heterogeneous mixtures. They are those mixtures in which the components that constitute it can be seen with the naked eye, since they are usually distributed unequally. Depending on the size of the substances, they can be coarse mixtures (the particles are large in size) or suspensions (the particles are small in size). For example: Water with oil.
Examples of Homogeneous Mixtures
Some examples of homogeneous mixtures are:
- The air. It is the mass of gases that is attracted to the earth's surface by the gravity and which is composed of: nitrogen, argon, oxygen, carbon dioxide, among others. These gases cannot be distinguished with the naked eye.
- Coffee with sugar. It is a homogeneous mixture because when a spoonful of sugar is dissolved in the coffee, the white color of this ingredient is no longer appreciated (although its flavor can be felt when taking a sip) and the mixture continues to have the dark color of coffee. .
- Water with salt. The water of sea It is a homogeneous mixture that is composed of Water, salts and other dissolved substances. However, when observing the water, these components cannot be differentiated, which are what give it salinity.
- Chocolate milk. It is a drink that consists of a homogeneous mixture made up of milk and one or several tablespoons of chocolate powder. The mixture has a dark color and, in the event that it does not have lumps, the components cannot be recognized with the naked eye.
- Steel. It is an alloy of iron, its base metal, with other metallic or non-metallic components such as carbon, nickel either copper (depending on the type of steel you are looking for). The result is a metal in which the components cannot be distinguished and which combines their physical properties. The same thing happens with other metallic alloys such as bronze or white gold.
- Water and alcohol. It is a liquid and homogeneous mixture that is obtained by mixing water and some distilled alcohol.In this mixture, it cannot be seen with the naked eye how much of each component there is.
