homogeneous mixture definition chemistry


Homogeneous mixture definition chemistry

In this lesson, you can learn more details about a homogeneous mixture, homogeneous pure substance, examples of mixtures and what is the difference between a solution and a mixture

First of all, what is the homogeneous definition chemistry?

Homogeneously is Latin for "the same kind".we called the homogeneous substance if it contains only one type of compound or one element or uniform composition of the mixture.



Many examples of homogeneous pure substances and compounds, such as metals, pure Ni, Al, Fe, Si,....  which contains the only one atom. On the other hand, the compounds which have more than elements like solid salts NaOH, NaCl, ....and so on, or liquid solutions like water, HCl.
Now, we know what is homogenous in chemistry, but Which is a homogeneous mixture?

homogeneous mixture chemistry

Definition of a homogeneous mixture in chemistry:
           A mixture which has uniform composition and properties throughout. 
In other words, the homogeneous mixture is defined as a combination of two or more pure chemical substances in which the original substances retain their chemical properties. 
Many students ask us, which is an example of a homogeneous mixture? we answer this question in the next paragraph.

You can see: general chemistry it's very useful to you

Homogeneous mixture definition chemistry example:

Air is containing a mixture of gases like N2, O2. H2O that is considered a homogeneous mixture of gasses. also, If the combination of two chemical substance like NaCl and H2O were mixed together for forming a  homogeneous mixture solution or aqueous solution, anther clear example of homogeneous mixtures, when we add NaCl solution or solid to KCl solution or solid the new solution or solid is produced which have the same chemical properties, that is direct us to ask ourselves:  


What is the difference between a solution and a mixture? 
Actually, the solution is a type of mixture, but we can say solution on a mixed of salt with water, we can't say the solution on a mixed of salts or different liquids.


On the other hand, now, you are able to know what the homogeneous mixture meaning. 

In the next post, we will add more details about a homogeneous Catalyst and a homogeneous Equilibrium  

If you want free scientific paper or thesis about mixture or homogeneous mixture  or searching directly on the  free scientific publications

college chemistry help


In many universities and colleges, the students may be required help. In this lesson under title college chemistry help we ready to help anyone to complete a general chemistry course or homework, containing (organic chemistry, physical, inorganic, applied, biochemistry.

many topics involved in a basic course in general chemistry.
Also, you can get on the free books, articles from  Free Scientific Publications
many chemistry help websites help a student of college to get the chemistry homework help the need and we direct to the best  college chemistry help websites:

chemistry help website no. 8

we will add a new site as soon as possible

volume units compared


volume units compared
The largest volume, shown in part, is the SI standard of 1 cubic meter (m3). A cube 10 cm (1 dm) on an edge (green) has a volume of 1000 cm3 (1 dm3) and is equal to 1 liter (1 L). The smallest cube is 1 cm on edge (dark blue) and has a volume of 1 cm3 = 1 mL.


Scientific model of chlorine gas


A scientific model of a gas The chlorine gas in this container is made up of chlorine molecules. Each molecule is a combination of two chlorine atoms. Chlorine molecules, like all gas molecules, are in constant random, chaotic motion and undergo frequent collisions with each other and with the container walls. This model is used in Chapter 5 to explain several properties of gases. n l
