A colloid can be distinguished from a true solution by its ability to scatter a beam of light, known as the Tyndall effect.

Dissolved molecules as large as 1000 pm never separate as a result of gravitational forces, even in an ultracentrifuge. When suspended particles reach µm size, they separate readily under gravity, and we classify the mixture as definitely heterogeneous. Suspensions of particles between these sizes (5k - 200k pm) never settle under gravity or centrifugation, yet the mixtures are definitely heterogeneous because beams of light passing though them are visible.

This section dives into how we define what a solution is and is not.

Food mixed with hydrochloric acid from the stomach would burn the small intestine, the next portion of the digestive tract after the stomach, if it were not for the release of bicarbonate (HCO 3 – ), a weak base that attracts H + . Bicarbonate accepts some of the H + protons, thereby reducing the acidity of the solution.

It discusses the distinction between homogeneous mixtures, like lemonade, and heterogeneous ones, like rocks. Additionally, it categorizes mixtures into solutions, suspensions, and colloids based on particle size, and notes that mixtures can be separated using physical methods due to differences in the physical properties of their components.
