GCSE Chemistry - What is Corrosion and How to Stop it #71

Thank you so much

This topic was an absolute killer for me but I understand it soooooo much better after this amazing video

Filled up a page and a bit with this info, thanks for helping me revise!
(The page was 29.3 centimetres long and 21.2 centimetres wide, so it’s a big page!)

I really grap your tutor thank you very much for such great explanation


If you don't mind please work on kinematics physics portion I really need that

Thank you brother 🙌

Erg helpful

24 CAROT DOESN'T RUST, THEY WORK WITH 18 CAROT

I have exams today in Cognito I trust

In the example with the nails in the test tubes, what keeps the nail from rusting in the first one with just water? Water is partially made up of oxygen, so what prevents the oxygen part of water (H2O) from creating rust?

So helpful

How you make a animation of corrosion?

great video

Why is zinc more reactive with oxygen? Asking for my project hehehe

you the the king of science. I love your explanation soooooooooooooooo much.

i helped me for my presentation for chemistry> thnx

Thank you so much! But one of my doubts still persists, does alloying come under the barrier or sacrificial methods of protecting iron? But, thanks again!

i love u n ur vids❤️

You are a saint, there should be a “St. Cognito’s Day” every year, you make all of the info so concise and easy to understand thank you!

How does sea water affect rusting?

hi people from my class 😩

The explanation in every one of your videos is so helpful. Thanks

I love the animation style! Thank you for helping us science newbies !! <3

I cannot stress how much of a great channel this is, told my whole class about this channel, easy to keep up with and honestly saved my chemistry marks. Thank you. @cognito

This is really helpful, thanks

Thank you brother. I really enjoyed this video of yours from Papua New Guinea🇵🇬

Wow super explanation bro....

can you please tell me which app or software you use for creating these animation videos?

Hi, I was wondering what you used to make this video to see if it would be helpful for my personal revision. I just feel it would help me a lot in all my subjects.

If some one wants I will add your videos to end screen if you help me to develop my channel

good one good one very good one

these videos are really helpful - thanks
