First time in life I saw this reaction.Thanks a lot!!

Hi,
Nice video.

I have 3 comments about your experiment.
1°)
Your iron nail may be galvanized (Zinc coating corrosion inhibitor that protect the iron from straightforward rusting... Zn serve as sacrificial metallic reducer to restore any corroded iron spot)
This doesn't interfere with your experiment since Zn is above Fe in reducing power just like iron is above copper.
So Cu(2+) remains the more oxydant cation vs Fe(2+) and Zn(2+)...
This means that at first you get fast dissolution of colorless ZnSO4 and precipitation of Cu(0)... then green FeSO4 and more Cu(0).

2°)
The green Fe(2+) tends to oxidize upon contact with air (or dissolved O2 from the air) to produce yellow/orange/red Fe(3+). What is observed into your open to the air tube.
Fe2(SO4)3 is slightly acidic when into solution and does form at least partially red rust and sulfuric acid.
Fe2(SO4)3 + 6H2O <==> 2Fe(OH)3 + H2SO4...
Part of the red mud supposed to be cemented Cu(0) may thus be rust (iron (III) hydroxide).

3°) You of course know that inox metal often contains Fe/Cr/Ni by decreasing %.
All 3 metals are more reducing than Copper... (Cr>Fe>Ni)
In principle your inox spoon must have been coated by reduced copper while swirling to dissolve your CuSO4... meanwhile you have some Cr(3+) \ Fe(2+) \ Ni(2+) sulfates - all 3 in different shades of green - that did pass into solution.

MIND BLOWING TEACHING GURUJI RADHEY RADHEY AWESOME TEACHING SIR 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻

[shubhgoelgaming]

Really amazing. U r doing such a great job

[saurabhugale]

Thanks sir very Informative,
1. Sir can we increase the amount of water(solvent) to dissolve CuSO4 completely in water?
2. If CuSO4 is not completely dissolved in water then does it will affect reaction?

Thank you so much sir
i was so confused when I saw the reaction I was confused but this helped me a lot

[SKBHATKALIE]

Thank you sir it's pleasure to see this., Hope you get 1 million soon, loving from KSA, Riyadh

[.shreyakumari]

Thank you sir.. this really helped me with my practicals 🙏🏻

[kavineshkumars]

hi sir, pls can u confirm whether copper is reddish brown or pink in colour. bcaz in the net its reddish brown but in this video it is pink .i was astonished good vids sir keep it up

[dabi]

Thank you, for such a helpful video sir .

[hritumalikasinha]

So easy and helpful experiment. Thank you

[shesunaga]

Sir please tell me how to make @ anti iron gel.

[vijayavijaya]

This helpful for my study thank you 😊😊😊😊😊😊😊

[jpkl]

sir the copper deposition is totally pure copper or not

[creativecorner]

Wow
hope you reach till 1m likes and views

[savitajuyal]

What is the nature of cu deposited is t hard flaky, soft
