Difference between Homogenous and Heterogeneous Mixture
Chemistry is one of the critical subjects that deal with different terms like mixtures, compounds, elements, etc. Chemistry is the subject used for various research experiments. Amidst these research and experiments, we come across two terms, i.e., homogenous and heterogeneous mixtures. Now, what are these mixtures, and what importance do they hold during several experiments.
Well, a homogenous mixture is defined as the mixture in which the composition formed is smooth and uniform. The matter used in homogenous mixtures is easily dissolvable. These substances are in an equal amount in the composition. For instance, the composition of salt and water is a homogenous mixture, and the composition of sugar and water is also homogenous. The elements that are not differentiated from one another are called homogenous mixtures. Some other examples of homogenous mixtures include wine, seawater, vinegar, air, blood, etc. It is interesting to note that there is a significant kind of homogenous mixtures called solutions.
On the other hand, a heterogeneous mixture is defined as a mixture in which the composition is not smooth and uniform. There is no uniformity present in the elements. The elements are not easily dissolved. These types of mixtures are seen in solid, liquid, and gaseous states. For instance, sand and sugar cannot be easily dissolved. One can see the sugar crystals and sand separately. Thus, sand and sugar is heterogeneous mixture. There are two significant kinds of heterogeneous mixtures as well, namely suspension and colloids. Now, having said that, let us discuss some points of contrast between the two briefly.
So, these are some of the points of contrast between homogenous and heterogeneous mixtures. These mixtures vary in certain aspects, as mentioned above. Well, it is interesting to note that both homogeneous and heterogeneous mixtures possess some essential characteristics for carrying out several experiments. Some of the characteristics are given below.
Characteristics of Homogeneous Mixtures
Characteristics of Heterogeneous Mixtures
So, these are some of the characteristics of homogenous and heterogeneous mixtures. Well, it is interesting to note that heterogeneous mixtures undergo a process called homogenization. Homogenization is defined as a process of turning a heterogeneous mixture into a homogeneous mixture with the help of non-soluble liquids like methanol.
Now, here arises a question, i.e., is soft drink a heterogeneous mixture or a homogeneous mixture? Well, in soft drinks, various substances are used like sweeteners, water, carbon dioxide, etc., which form a uniform mixture. These substances are easily dissolved. Therefore, soft-drink is a homogeneous mixture.
Students also wonder if water is homogeneous or heterogeneous. Well, it is important to note that in a heterogeneous mixture, the components are seen in two layers or phases. So, talking about water, it is a homogeneous mixture in itself because water comprises of elements like nitrogen, oxygen, and other gaseous substances.
Homogeneous mixtures and heterogeneous mixtures are different from one another. The drinks that we buy in stores are homogeneous, whereas the mixtures which are not dissolved like sand and water are called heterogeneous mixtures. It is interesting to note that homogeneous mixtures do not depict any tyndall effect. Homogeneous mixtures are also called solutions. One of the examples of solutions includes alloys. All solutions are homogeneous mixtures.
On the other hand, heterogeneous mixtures depict the tyndall effect. The size of the particle is bigger, i.e., it ranges from one nanometre to one micrometre. The components of a heterogeneous mixture can easily be identified. As already stated above, homogeneous mixtures have two layers or phases. Heterogeneous mixtures are also called as colloids.
Both homogeneous and heterogeneous mixtures are different from one another. There are general characteristics that make them vary from each other. Thus, it is important to know about both homogenous and heterogeneous mixtures as they are essential for carrying out several experiments and researches.
