Reaction of Magnesium and Water

[@Kepler_2258]

Also if you melt magnesium and start its reaction with air, then drop it in water it makes a puff and a shower of greenish colored sparks, like a mini firework. I've done that many times, but one thing to take note, the molten magnesium when it reacts with air, is intensely bright and emits UV rays, so it can damage your eyes easily, so if your going to try to do it be careful. Also I recommend using a torch to melt it, and when it starts smoking and starts to get bright you don't need to heat it anymore, it will become hot enough to react more of itself.

[@oktyabbasi]

the water turned purple because he used phenolphthalein which is a acid-base indicator, the reason it turns purple is because the magnesium reacts with water to make the magnesium hydroxide, this dissociates in water to make OH- ions which turns the solution basic and the phenolphthalein pink.

[@noorusmani8433]

so it's actually a pinkish color, right? It didn't look purple at all to me

[@oktyabbasiborhani7616]

yeah pinkish

thanks for the useful piece of info

thank you! i got a bit confused there

This is actually how chemistry should be taught

[@grungjy]

Our school literally doesn't have like 2/3 of these ingredients in their lab, so we have to memorise these things and kinda imagine them 💀

[@billpaier5198]

Not if you do not explain the origin of the purple colouration which I see from another remark is due to the addition of phenolphthalein indicator . The Mg + 2H2O = Mg(OH)2 +H2; no coloured species until you add an indicator. Also, why does he infer that there is no H2 in the bubbles ? Where does it go ?

I request you to please add captions to your videos as at some parts we are unable to understand your speech. Otherwise, your channel is awesome!

[@m.zaqlulanandarizky1887]

magnesium yang bereaksi dengan air akan menghasilkan magnesium hiroksida, dan ketika bereaksi air akan berubah menjadi warna ungu karena ditambahkan phenolphthalein yang merupakan indikator asam basa, hasil nya berwarna ungu karena magnesium hiroksida yang berdisoasi dalam air untuk membuat OH- ion yang mengubah larutan menjadi basa. persamaan nya adalah : Mg (s) + 2H2O (I) -> Mg(OH)2 (s) + H2 (g)

[@jonathanmuniz4659]

So then there are no significant signs in icy planets because there is no such thing as room temperature in a ice planet like Uranus or Neptune, meaning that it would remain the magnesium there until decomposition and it would take a while.

[@inshaahsan2674]

I really like his videos which are based on reactions..😊

"The bubbles are not hydrogen gas, just steam" *Shows equation where's the hydrogen gas present* Yeah, well played

because you cant SEE hydrogen gas i guess

Who made this error? I saw this from acollierastro and her video on alkaline water.

[@bubblezovlove7213]

I wonder why he doesn't pronounce the G in magnesium?

[@itsaoifexo2772]

•A very slow reaction •A few bubbles of gas given off

[@tripster103]

Magnesium hydroxide (Mg(OH)2) should have (aq) next to it as it is aqueous in water. You have put (s) next to it, indicating that it is solid.

[@MKadda]

Magnesium hydroxide is a weak base. Does not dissolve completely in water. The reaction is correct

[@Mew__]

Magnesium hydroxide is a hydroxide with a large enough Group II metal; it is badly soluble.

[@marinaspies1349]

does anybody know about a hydroelectric battery, composed of a carbon stick covered with magnesium powder? You can add water and a chemical reaction happens which creates energy. I stumbled across this in an article but I don't really understand how it works. Can anybody help?

[@totopolo2379]

it has a basic color indicator right?

[@salvadorginez3246]

Why does he says there is no hydrogen produced, there should be, isn’t? Even at the end of the video the reaction shows there’s Hydrogen as a resultant.

[@898tigereyes]

i like the fact how these videos are getting free views even tho we make fun content

[@garyo8962]

lol i have to watch this bc of my teacher

[@suriladevi6207]

What will happen to the size of magnesium after the reactivity? And please give a reason for that .

[@hemaanggaur8352]

the magnesium will completely dissolve in water producing magnesium hydroxide which apparently turns the solution purple-pinkish......this phenomenon eventuated due to the involvement of heat to the solution .....

[@LucasSilva-zr5dr]

@@hemaanggaur8352 Actually, I suppose the water turned pinkish because he used phenolphthalein.

[@politicstoday8002]

i think in microscopic size,some magnesium atoms already rzact with liquid water

[@daalbert1651]

Very informative.Thank you👍👍👍👍

[@presidentjoethudbrandon7074]

It's not just magnesium; it's alloyed with iron. Pure magnesium wouldn't react quickly enough to be used as a heat source. Edit: and there is no shortage of military MREs. They are literally placed outside the mess for soldiers to take as needed.

[@necolleshinori]

Uh bubbles produced should be both hydrogen and 'steam' (when water reaches boiling point) ?

[@tripster103]

He said the bubbles that you SEE are not hydrogen gas. Obviously there is hydrogen gas released, because we can see that Magnesium hydroxide was produced.
