Types of Mixtures
There are various types of mixtures. These types are derived from how they were formed in the first place. They are;
Solid-solid mixture
This is the mixture of two or more substances with each substance in the solid phase or state. Examples include iron filings poured into sand, salt in sand, sugar and flour.
Solid-liquid mixture
This is the mixture of two substances with one substance in the solid state whilst the other substance is in the liquid state. In this type of mixture, the solid substance is seen suspending in the liquid substance. Examples are chalk particles in water and clay particles mixed with water (mud). Also mixing salt crystals and water. However, in this mixture, the solid dissolves in the liquid but can be separated easily.
Solid-gas mixture
This is the mixture of a substance in the solid state and another substance in the gaseous phase. Example; Burn a paper in a clean container. Observe the smoke and black fume inside the container. Use a finger to take some sample and feel the texture. Another example is car exhaust and smoke from chimney.
Liquid-liquid mixture
This is the mixture of two substances with both in the liquid state. For instance, pour oil into water. Shake thoroughly and allow the set up to stand still whilst watching the observation. The oil forms the top layer whilst water forms the bottom layer.
Liquid-gas mixture
This mixture is formed from combining a substance in the liquid phase and another substance in the gaseous phase. Example; shaking Coca-Cola and immediately opening it. There is a huge effervescence coming out as a result of the carbon dioxide in the drink. Another example is that the sea and rivers contain huge amounts of dissolved gases for aquatic animals to get air.
Gas-gas mixture
This type of mixture involves the mixing of two or more gaseous substances. Example; Air which is a mixture of different gases. Perfume sprayed in one direction spreads into every direction. The scent mixes in the air.
