I thought that galvanising and sacrificial protection are two slightly different methods. Galvanising protects iron by covering it completely with a layer of zinc, which is itself protected by a layer of zinc oxide. If oxide layer is scratched, then zinc reacts rather than iron. Sacrificial protection involves a block of a more reactive metal being attached to the iron and this corrodes, rather than the iron.
That is correct, my guess is that they are referring to the fact that the waves and wind on the sea would erode the layer of zinc oxide away, and constantly kick-starting the process again.
Thankyou very much I didn't really get what my teacher was saying in class but now I totally get it! You have heaped me a lot on my school assignment. Thankyou heaps!!
thanks my teacher set this as homework then we pretty much say how to prevent rust and in the lesson i had no idea what she was talking about and now i get it so thanks so much
When mentioning "Rust prevention", galvanizing is wrongly mentioned, as you are in fact showing an example of cathodic protection. Galvanizing is a type of coating (normally a zinc coating) with two different protection modes: a barrier effect (there is a coating on iron) and an active cathodic protection effect (zinc corrodes, protecting iron). However, the use of zinc anodes in ships is not galvanizing. Zinc anodes are not covering all the surface of iron, so here we have cathodic protection but no barrier effect.
+Dhruv Gupta Do you mean at 3:38? She says 'a sacrificial protection method called galvanising'. She is describing sacrificial protection, you are correct.
I have a doubt on one of he things that you said... "Zinc getting corroded faster than iron"... If so happens then wont it cause a problem economically???? Rather can't we use a substance which has a lower corrosion rate?? Like Tin or copper??? Copper is cheap... Why is it that we go on galvanizing more that tinning??? And what is the advantage about zinc oxide formation? We just have to deoxygenate it over and over again.... Galvanizing causes the ship's outer layer to rust went it sails... So how are we keeping corrosion at check??? Thank you.
+Hrishikesh hatti Keeping zinc on iron, Zinc will act as a motherly layer. When Zinc corrodes it doesn't form a coloured layer. So when zinc is placed on iron it will not let the iron rust but the zinc will rust but it will not produce a rust layer or degrade the iron. Hope i helped u
Rusting of iron required water and oxygen. The presence of salt or NaCl where it will act as catalyst in hastening the rusting process on the iron. At higher temperatures, rusting process is higher. Why? The iron atoms will not spontaneously emit out their stationary electrons before turning themselves to Fe(2+) cations. Water molecules within the droplet of water are constantly drifting within itself. At higher temperatures, the drifting water molecules will have higher velocities. Dissolved oxygen molecules within the water droplet where they will adhere on those drifting water molecules. Whenever the oxygen "atom" on a drifting water molecule is slamming against a iron atom, this may force it to transfer some of its electrons to the oxygen "atom" before it turning to Fe(2+) cation and the oxygen "atom" will turn into a oxygen anion or O(2-). This is how iron gets rusted. At higher temperature, the oxygen "atom" that adhered onto the drifting water molecule will slam harder against the iron atom therefore the rusting process will be hastened. The molecular mass of water is 18. Whereas the one of sodium is 23.9. Therefore the oxygen 'atom" that adhered onto a drifting sodium cation will slam against the iron atom much harder to force chemical reaction to take place. Thus, the presence of salt or NaCl within the droplet of water will hasten the rusting process of iron. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.
So what about removing rust? I’m thinking more specifically in an old gas tank from a motorcycle from the early 80’s. The bike runs and everything but I can see what looks like some thin spots of rust. Anyone have any ideas on how to remove it?
If you can galvanize with zinc because it's more reactive, does that mean that using magnesium or aluminum would yield similar effects? and What determines the reactivity of elements (metals in this case)?
Yes - magnesium in particular is often used as a sacrificial metal (as is zinc). More reactive metals have a greater tendency to lose electrons to form positive ions.
So what im going really to do? I replace my tap 3x in a year because its rusted always. Our water supplied by our developer isnt a good quality and the water is abit salty. All my taps,lavatories and toilets are all rusty. How to rid off of this? Thank you
Install a professional water filter at the hot water heater if you can, a plumber can install a filter unit that you can attach to the main pipe (i think ) it will add chemicals to soften the water which is what you want, because hard water and rust go hand in hand.
+BSBCHREAF yes you are right, zinc oxide is a white powder. Which part of the video are you meaning exactly? Rust is usually thought of as on iron because that is what we seem most commonly in day to day life - and iron oxide forms a red colour.

THIS HAS HELPED ME SO MUCH SINCE I'M DOING A PROJECT THE NIGHT BEFORE AND PULLING AN ALL NIGHTER AND WOOW TY
Haha glad it helped!
I'm being told to watch this in a lesson
where do you study ?

.
But then zinc is more reactive than iron so this corrodes instead of iron
Or I’m wrong
Galvanizing can actually accelerate galvanic corrosion. Do a search for galvanic corrosion.
That is correct, my guess is that they are referring to the fact that the waves and wind on the sea would erode the layer of zinc oxide away, and constantly kick-starting the process again.
no
my teacher told me to search this rusting of iron experiment in home it was helpful to me
Great explanation, simple and minimal, like the visualizations. Thumbs up! :)
Thanks I’m taking cleaning and corrosion control love this help
Great!
thank u.It was informative
helped a lot in my presentation for school
really well put together! Thanks so much!
I needa watch this for a lesson
This is perfect info for my science project!
what did you use to edit? btw thanks for the video it helped alot:)
Thankyou very much I didn't really get what my teacher was saying in class but now I totally get it! You have heaped me a lot on my school assignment. Thankyou heaps!!
It’s 2021 and this is still helpful
Fuse School always has good videos
thanks my teacher set this as homework then we pretty much say how to prevent rust and in the lesson i had no idea what she was talking about and now i get it so thanks so much
Super informative. Thanks!
Good example
Thank you for this video mam .
Thank you.

It's funny how she really tries to make an interesting voice. "Mehetal coarroahhudessssss"
TOOO DE SCRIBBE
3:38 why is zinc used for galvanisation instead of magnesium/aluminium?
great explanation and very helpful for school
Wonderful! Glad it was helpful!
Thank you
hey wt r studying
No problem!
These informations are really satisfactory. I am very thankful.
Glad you think so!
Please do a video of how pressure cooker works! xoxo
Superb Explaination 👏👍👌👏👍👍😘👏 I understood....😊
Thanking you 🙏🙏🙏
You're most welcome 😊
Thank you a bunch. Love from Bangladesh💖
You are most welcome 💜
Very interesting and awesome presentation thanks...Btw, you have such a lovely voice!!
Thanks
Most excellent explanation.
i have a aluminum boom attached to a steal pedestial,so can a zinc attached to the boom prevent the two metals from corrosion?
Isn't the method stated as galvanizing actually sacrificial protection?
+Dhruv Gupta Do you mean at 3:38? She says 'a sacrificial protection method called galvanising'. She is describing sacrificial protection, you are correct.
Awesome explanation..thnxxxxx alot...
thanks
great video
Hello. I'm from bali. this is a great experiment.
goodluck brother

i found this video to be helpful .👏👏👏👍👍
continue with the good work
Thank you! Glad it was helpful!
nice videos
How come the iron doesn't rust even though the zinc plates don't cover all of the iron? Surely, since the iron is exposed, it should still rust?
Samantha Sharp ik it’s 2 years late but it’s because the oxygen surrounding it is going to corrode the zinc instead since it’s more reactive
If you can galvanize with zinc because it's more reactive, does that mean that using magnesium or aluminum would yield similar effects?
and
What determines the reactivity of elements (metals in this case)?
Yes - magnesium in particular is often used as a sacrificial metal (as is zinc).
More reactive metals have a greater tendency to lose electrons to form positive ions.

Are there any benefits of rust
My brother's combination tool went into the washer and I looked at the treatment section and it said nothing
great video!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks!
Officially my favorite channel on youtube!! I can come here for EVERYTHING! You guys are amazing.
Wow, thank you so much! Appreciate it ❤️
Who is here during corona?
I'm bieng forced to watch this
Yeah me too
Wow!!!!
this video was awesome awesome awesome
Wow, thank you!
Either her breathing or just the way she talks irks me🥴
pretty sure the paint also pulls in heat or pushes it away but ok
Isn't Zinc Oxide white colour? why the picture gives reddish rust colour?
+BSBCHREAF yes you are right, zinc oxide is a white powder. Which part of the video are you meaning exactly? Rust is usually thought of as on iron because that is what we seem most commonly in day to day life - and iron oxide forms a red colour.
What if the whole layer of zinc corrodes from the ship?
This is epic
Next video you should make: "What is a pop filter"
GOOD MORNING MAM I AM OM RAM CHAITANYA ROLL NO : 32🙏🏿🙏🏿🙏🙏
Thanks fo th👍👍👍👍
No problem 👍
much better than my teacher lol
what about distilled
why doesn't gold rust?
very unreactive, meaning that gold could be buried in the earth for a 1000 years and it'd be in perfect condition
treatment ?
2/2/2021 Came here to cus my teacher told me to prepare my lessons by watchin it
Happy teachers day
hi
I had a homework about this video
im trying to listen but the nose breathing is bothering me. P.S i binge-watch these videos. I love them!
Thank you! Glad you liked them 🙂 Sorry about the nose breathing!
Really informative.now I can prolong d life of my motorcycle for being exposed to water and moisture...tnx
