Solution, Suspension, and Colloid
Solutions are homogeneous mixtures where two or more substances blend completely. The particles in solutions are extremely tiny (molecules or ions), making them impossible to see with the naked eye. When you shine light through a solution, the beam passes straight through without scattering.
Suspensions are heterogeneous mixtures containing larger undissolved particles that you can often see separating over time. These particles are large enough to be visible and can be removed through filtration. Think of muddy water as a classic example - the dirt eventually settles at the bottom.
Try This! Shine a flashlight through water with a few drops of milk added. Can you see the beam? This demonstrates the Tyndall effect in colloids!
Colloids exist in an intermediate state between solutions and suspensions. Though they're heterogeneous mixtures, their particles remain evenly distributed and don't settle out over time. The unique property of colloids is the Tyndall effect - they scatter light beams passing through them, making the beam visible. Milk is a perfect example of a colloid, containing tiny fat droplets and proteins dispersed in water.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

When you mix substances together, they form different types of mixtures depending on particle size and behavior. Solutions, suspensions, and colloids are three important types of mixtures you'll encounter in chemistry that have distinct properties and applications in everyday life.
