Colloids

03/15/25

“Are there substances that are neither suspended nor diluted in another substance?”

When people talk about substances that exist in another substance, it’s common to place them as being either suspended or diluted. However, a mixture exists between them. These substances, termed Colloids, exist between 1 to 1000 nanometers in size (to small to be visible to the naked eye) and do not settle out over time. Examples of colloids include jello, shaving cream, and milk.
