Explanation:
COMPOUND
- Compound are substances which can be formed by chemically combining two or more elements.
- Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.
- Compounds fall under pure substances.
- The chemical composition of compounds is always fixed.
- Compounds are always homogeneous in nature
- The constituents of a compound can only be separated by either chemical or electrochemical methods(like extraction).
- The properties of compounds are unique to themselves and need not necessarily reflect the properties of the constituent elements.
- A new substance is formed after the constituents are chemically combined. So, a compound has different properties from its constituents.
- The melting & boiling points of a compound are always defined.
- Examples : Water, salt, baking soda, etc.
MIXTURE
- Mixtures are substances that are formed by physically mixing two or more substances.
- Mixtures are mainly of two types i.e. homogenous mixtures and heterogeneous mixtures.
- Mixtures can be categorized as impure substances.
- A mixture can have a variable composition of the substances forming it.
- Mixtures can either be homogeneous or heterogeneous in nature.
- 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.
- 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.
- No new substances are formed in mixtures and their properties are dependent on the properties of their respective constituents.
- The melting and boiling points of a mixture is not defined.
- Examples : Oil and water, sand and water, smog (smoke + fog), etc.
