Question

List the points of difference between compound and mixture?​

Answer 1

Compounds:

1. Compound are substances which can be formed by chemically combining two or more elements.
2. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.
3. Compounds fall under pure substances.
4. The chemical composition of compounds is always fixed.
5. Compounds are always homogeneous in nature.
6. The constituents of a compound can only be separated by either chemical or electrochemical methods (like extraction).
7. The properties of compounds are unique to themselves and need not necessarily reflect the properties of the constituent elements.
8. A new substance is formed after the constituents are chemically combined. So, a compound has different properties from its constituents.
9. The melting and boiling points of a compound are always defined.
10. Water, salt, baking soda, etc.

Mixtures:

1. Mixtures are substances that are formed by physically mixing two or more substances.
2. Mixtures are mainly of two types i.e. homogenous mixtures and heterogeneous mixtures.
3. Mixtures can be categorized as impure substances.
4. A mixture can have a variable composition of the substances forming it.
5. Mixtures can either be homogeneous or heterogeneous in nature.
6. Mixtures can be separated into their constituents via physical separation methods such as filtration. Thus, the separation of mixtures is relatively easier than the separation of chemical compounds.
7. The constituents of a mixture do not lose their properties and so, the properties of a mixture are generally the sum of the properties of its constituents.
8. No new substances are formed in mixtures and their properties are dependent on the properties of their respective constituents.
9. The melting and boiling points of a mixture are not defined.
10. Oil and water, sand and water, smog (smoke + fog), etc.

Answer 2

Answer:

The mixture contains two or more substances mixed, but neither chemically as well as not in inexact quantity while compound includes two or more elements combined chemically and in a fixed ratio.
