Colloids

Colloids are a type of mixture that is in between a homogeneous solution and a heterogeneous suspension. They have particle sizes that are big enough to be visible, but the particles do not settle out over time. Colloids exhibit the Tyndall effect, and they scatter light. Also, colloids can't be separated by filtration. All colloids have a dispersed substance in a dispersion medium. Some common colloids are fog, smoke, foam, gels, and emulsion. The dispersed substance and dispersion medium can be solid, liquid, or gas. An emulsion is two immiscible liquids that are dispersed through one another. Colloids are like a homogeneous solution in some ways, but like a heterogenous suspension in other way.

It’s been about 5 years. The legend has returned. I can go back to acing chemistry now :)

[immensiverocker]

I completed my chemistry course and i never have to study that again but i cant skip your videos

[sudarshanrathi]

He is the best chemistry teacher in YouTube. That's it

[deadbzeus]

The legend returns, I can not imagine how many students you helped through college/university and high school. Thank you for everything.

I never get bored, distracted or in need of subtitles in this guys videos. The way he demonstrates and presents without using complicated words makes it so much easier to understand and motivational. With other youtube videos, they use words without describing it and powerpoints that are so boring. Wished Tyler DeWitt made more videos about every subject in chemistry

I was able to get 100%s on my High School Chemistry tests because of your videos - thank you SO much Tyler DeWitt! Now I am in College and I was actually excited when I found out I needed to take Chemistry this semester. I was looking forward to coming back to all the amazing videos I watched in High School in order to pass the class. THANK YOU!! You are doing INCREDIBLE things for this generation -- God bless you and THANK YOU!!

Welcome back! You clearly have a gift! Its been 5 years and you continue to explain the complex stuff in the simplest words! Continue being the exceptional teacher that you are!

I'M REALLY GLAD U R BACK!!!
U r the only person who makes me understand chemistry... THANK U💙

Oh my god Tyler you've grown up 😂😂 I watched a couple of your videos years ago and I subscribed to your channel but just saw this video but " gold remains the same" ❤

Commenting for the algorithm to recognize this great man's hard work to be shared to students across this platform.

I almost quit school due to a bad chem professor (and tutor!), but Tyler got me through it and now I have a B.S. in science. Thanks Tyler!

[dhill]

God I love this guy!! I'm so grateful that I stumbled upon his videos. Thank you sir you're the reason I passed college chemistry. You are truly a blessing.😊😊😊

This video should get much more play than it does. It's one of the better ones on this subject on YouTube. The other ones I found were more like watching people do their homework.

[haln]

Honestly this man deserves an award or something, he has been posting chemistry videos for at least 13 years now respect +

[Utkarsh-di]

the best platform for learning chemistry. not too modern, not too traditional. Love this guy's teaching style!

[HowHelper]

Really cool video introducing colloids! I used to feel slightly scared when I heard the word because it sounded very sophisticated, but your video really helps break the ice!

[joshandymathewclassviii]

Your videos are the so beautifully illustrated and taught, I learned more off of your 1 video than 3 years of my chemistry classes. Thank you for being a Good Human being. 🤗🤗🤗

[nectarichard]

Hi Tyler! You were my go to chem teacher back 2017 .... i passed chemistry really well!! Thank you so much for the content!!!!

[nmzuha]

I love your old teaching method rather than the present. Hope you'll return as like as you were with your amazing, interesting and friendly teaching method again.

[leiwong]

You are highly respected, Professor! Missing your old cheerful smiles though. Hope everything is going well with you!
