Difference Between Pure Substance and Mixture

An Introduction to Substances and Mixtures

A substance is a pure, homogeneous, and uniform chemical compound. A mixture is a heterogeneous combination of two or more substances. The substances in a mixture can be physically combined (like salt and pepper in a shaker), or they can be chemically combined (like the molecules in a glass of water). The properties of a mixture depend on the properties of the substances that make it up.

    Pure Substances and Mixtures

    A pure substance is a substance that is composed of a single type of atom or molecule. A mixture is a substance that is composed of two or more types of atoms or molecules.

    Pure Substance

    A pure substance is a material that is made up of a single type of atom or molecule. For example, water is a pure substance made of two hydrogen atoms and one oxygen atom. Diamond is a pure substance made of carbon atoms.

    Mixtures

    are two or more substances combined together.

    One example of a mixture is a salad. The ingredients in a salad are all mixed together. Another example is paint. Paint is a mixture of pigments and solvents.

    Difference Between Pure Substance and Mixture

    A pure substance is a substance that is made up of a single type of atom or molecule. A mixture is a substance that is made up of two or more types of atoms or molecules.

    A pure substance is defined as a material that is made up of a single type of atom or molecule. A mixture, on the other hand, is a material that is composed of two or more different substances that are physically combined. The properties of a pure substance are always the same, whereas the properties of a mixture can vary depending on the composition of the substances that make it up. For example, water is a pure substance made up of two hydrogen atoms and one oxygen atom. Its properties, such as boiling point and density, are always the same. But if you mix different types of substances together, the properties of the mixture can be very different from the properties of the individual substances. For example, if you mix oil and water, the mixture will have a lower boiling point than either of the individual substances.
