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.

[@malleshyadavmallesh7351]

.

[@moonafazal1990]

But then zinc is more reactive than iron so this corrodes instead of iron Or I’m wrong

[@RovanRCTube]

Galvanizing can actually accelerate galvanic corrosion. Do a search for galvanic corrosion.

[@nomadic7]

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.

[@joaosalvador]

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.

[@dhruvgupta5248]

Isn't the method stated as galvanizing actually sacrificial protection?

[@fuseschool]

+Dhruv Gupta Do you mean at 3:38? She says 'a sacrificial protection method called galvanising'. She is describing sacrificial protection, you are correct.

Hey, thanks!

[@user-wf2nr6zx4s]

any video for cathodic protection ?

[@Frustrated.Indian.]

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.

[@FlogaHD]

+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.

[@samanthasharp6271]

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?

[@Rich-AF]

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)?

[@fuseschool]

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.

[@indigogoigorgo7992]

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.

The x just stands for a varied number of water molecules. If it is 4 on the left hand side of the equation, then it will be 4 also on the right hand side. The H20 stays as H20 throughout. Does that make sense?
