Web1. I understand that the definition of a heterogeneous mixture is a mixture in which 2 or more phases are present, i.e. you can see the mixture is not uniform. I know a homogeneous mixture is a mixture in which only one visible phase is present, but why are suspensions and colloids considered heterogeneous, for you only see one phase as the ... WebIn separation and purification: Basic concepts of separations. …amounts of substances in a mixture. In chemical methods, one may start with a completely homogeneous mixture (a solution) or a heterogeneous sample (e.g., solid plus liquid); in the act of separation, some particles are either partially or totally removed from the sample.
