| mixture | two more substances mixed together, but not chemically combined |
| homogeneous mixture | a type of mixture that is the same throughout |
| heterogeneous mixture | a mixture that is different throughout |
| solution | a type of homogeneous mixture consisting of a solvent and one or more solutes |
| solvent | the largest amount of a substance in a solution |
| solute | the substance in a solution that is present in the smallest amount |
| residue | in the process of filtration, the substance left behind on the filter paper |
| filtrate | in the process of filtration, the substance(s) that pass through the filter paper |
| filtration | a separation method where a mixture is poured onto a filter and part of the mixture is retained on the filter (residue) and part of the mixture passes through the filter (filtrate) |
| evaporation | a method for separating a mixture where molecules escape from a liquid form of a mixture and transfer to a gaseous state. |
| chromatography | a separation process used to separate, inks, pigments, dyes and DNA |
| magnetic attraction | a separation method used to separate magnetic materials from non-magnetic materials by using a magnet |
| settling | a separation process where a mixture is allowed to sit undisturbed until a substance has fallen out of the liquid part of the mixture |
