Separation of homogenous mixtures

Mixtures around us

Everything that you see around you is matter and it can be in the form of pure substances or mixtures. Pure substances are, for example, water, alcohol, pure silver or iron.

Mixtures are everywhere! Perhaps you didn’t realise, but your houses are made with mixtures. Mixtures are in the food you eat, the clothes you wear and even in the air you breathe ;

Our lives are full of mixtures of every kind. Sometimes we need to make mixtures and other times, it is necessary to separate them into their original components. Let’s find out how! p>

The adventure begins!

Types of mixtures

Methods of separating homogenous mixtures: filtration and decantation

Methods of separating homogenous mixtures: evaporation and distillation
