Colloids

The video tutorial explains the differences between solutions, colloids, and suspensions based on their particle sizes. Solutions are homogeneous systems with small particles, while suspensions have larger particles that settle over time. Colloids are intermediate, with fine particles dispersed in a medium, exhibiting unique properties due to their large surface area. The tutorial highlights the importance of particle size in determining the characteristics of these mixtures.
