Difference Between Pure Substance And Mixture

The Major Difference Between Pure Substance And Mixture is that A pure substance is a material that has the same chemical makeup as other samples of that substance, while a mixture consists of at least two different substances.

If you have ever seen oil and water separate out after being shaken up together, then you have witnessed two different substances forming one mixture. While mixtures can be separated into their individual components through proper techniques, it would be very difficult to do so with oil and water because they are both liquids.

Other examples of mixtures include air (a combination of gases), saltwater (a combination of salt and water), or even coffee (a combination of caffeine beans mixed with hot water). On the other hand, pure substances are not always easy to define.

Pure Substance And Mixture – Explanation

When two or more substances are mixed together, they form a mixture. Mixtures can be separated into their pure substance components through physical means such as filtration and evaporation. However, sometimes it is impossible to separate the pure substance from the mixture because of chemical bonds that hold them together.

These types of mixtures are known as compounds. A compound is made up of at least two different elements chemically bonded together in fixed ratios.

For example, water (H2O) is composed of hydrogen and oxygen molecules which are covalently bonded to each other with an intermolecular force called hydrogen bonding that makes water behave like both a solid and liquid at room temperature- making it unique among all other liquids.

What is a Pure Substance?

A pure substance is a material that has a constant chemical composition and physical properties. it has only one phase. In other words, it does not have any impurities or solutes within it. There are several examples of pure substances out there including water, salt, and gold. All three of these materials all have the same properties throughout them as well as having a singular phase.

For example, water has a melting point of 0 degrees Celsius and a boiling point of 100 degrees Celsius while salt melts at 801 degrees Fahrenheit and boils at 1413 degrees Fahrenheit.

Gold has an atomic number of 79 which means that its nucleus consists of 79 protons and neutrons making it stable enough to be considered a pure substance as well as rendering it inert to oxidation from exposure to air or moisture in the environment.

What is a Mixture?

A mixture is a combination of two or more substances. Every substance has its own properties, and when you mix it with another substance, the new substance will have some of the original properties but also gain some unique properties.

For example, if you mix sand with water then the resulting mud would be wetter than just sand alone. Mixtures are everywhere around us! You can find them in things like ice cream or even toothpaste.

The components in a mixture are not chemically bonded together, and they can be separated by physical means such as filtering. For example, oil and water is an everyday mixture that does not mix at all when left alone; however, if you shake them up together for some time the two substances will eventually become one homogenous solution.
