Colloids, also called the colloidal system, is the term used to describe mixtures that look like a homogeneous solution, but are heterogeneous. It is not possible to realize that these mixtures are heterogeneous with the naked eye, for this reason, to find out if the solution is a colloid, the researcher must submit the substance to a process and wait to see if the liquid would form irregular or soft masses. Examples of colloids are: moisturizing cream, yogurt, milk, blood, paints and jam.
