Thank you for this video! My mind tends to hit a brick wall at such confusing equations but the way you explained it really helped me understand. Again thank you!
iron + copper sulphate ------> copper + iron sulphate A displacement reaction occurs since carbon is more reactive than iron, you can check in the Reactivity Series. Symbol equation: Fe + CuSO4 ------> FeSO4 + Cu
Can you please explain to me more about the electroplating iron with copper in the laborarory using the copper sulphate solution. Copper as a anode and iron as a cathode
I believe in that case there must be additional reducing agent that provides 2e or otherwise the Iron would just be eaten away. In the case of PCBs, manufacturers used to use Formadahyde and hydrogen oxide to get the extra electrons. Copper bags are submerged in Formadahyde solutions and electric fields blasts these towards the PCB anode.
One of the three test that passivate technicians would do is the "copper sulfate test" if said part has had removal og ferrous contaminants like free iron from their surface then when dipped into copper sulfate, the part shouldn't turn pink.
If you were to do this with a steel nail, what would happen to the carbon in the steel? Would it simply crumble out of the iron and form a black layer over the copper?
+Connor Steppie The percentage of Carbon in normal mild steel is only up to about 0.25% so you would not see a layer. In order to get the whole nail to react, it is best to dislodge (by stirring or scraping off) the copper to reveal the unreacted iron below. The Carbon would simply be mixed in with the copper sludge that is produced.
this is a rather old video. however, say you let the entire nail dissolve in an oversaturated copper sulfate solution. when seperated and dried; often i find 2 but sometimes 3 distinctly colored "powder", one black one white and the familiar "rose color"; am i right to assume the black and white are in fact the 2 copper oxides? as a side note/mention i find distilled water produced more "typical" rose colored particles. if you add a little bit of silicone oil to the copper sulfate solution and either , remove or let what ever catalyst fully dissolve; then seal and shake the container the copper particles will cling to the silicone oil and form spherical balls of varying size, it looks like you have airsoft bbs floating in the solution. and it becomes nearly impossible to dissipate the spheres, they are far more likely to combine with eachother to form a bigger ball. the key here is the silicone oil, however i dont know exactly why or how, bht assume it has something to do with surface tension as the spheres are only just a shell. and to be clear, there is no definate "core" or center, and i dont believe its just sticking to the silicone oil like dust to chewing gum, because the balls can drift up and down while the silicone oil leaves an almost clear seperation like oil and vinegar. oh ya almost forgot, if you poke them with a stick or rod etc, they will break apart and the particulates will eventually drift down to the bottom as you would expect.
is anyone not watching this for homework? some people actually do this at home. im using zinc instead of iron to make zinc sulfate for electroplating motorcycle parts. and see how it compares to a vinegar + Epsom salt solution. it still gives off copper in the process.
susan wurangu - The Iron displaces the Copper to form Iron Sulphate (a green chemical) in solution. The Copper Sulphate has not turned green. It has reacted to form a new compound.
I did not use a pre-made solution. A couple of spatulas full in 100ml water gave a nicely coloured solution. Estimating the mass to be about 5g this equates to a 0.2M solution.
Yes - But evaporate gently (without Bunsen if you have time). The pale green crystals can easily lose their water of crystallisation to become brown anhydrous Iron II Sulphate and if heated further this may release Sulphur Trioxide (white acidic fumes - very dangerous by inhalation) and reddish brown Iron III Sulphate
+Mr.chang cooler Indeed! In fact, I often use a drop or two of Copper Sulphate solution to get aluminium/acid reactions going as they are impeded by the aluminium oxide layer. Unfortunately, although this does get the reaction going, bits of copper appearing in the reaction can be a level of complexity too much for students.
+Princess Pineapple Exactly as it appears in the video. Until I bring in the second beaker, this is filmed in real time. There is no speeding up. The solution does not bubble, The iron nail simply becomes coated with pink copper. The solution changes from blue to green over the course of about an hour.
When Iron nail is added to Blue solution copper sulphate , it gives Green Solution i.e Ferrous Sulphate and a pink lustrous metal Copper .... This is the observation what I usually write .
Moonlight - This is absolutely a chemical reaction as new products are formed and, as Iron is the more reactive metal, copper will never be able to displace it to reverse the reaction.
Only sorry I can't get to the lab to do more videos during these difficult times. My very best wishes to everyone. Stay safe & stay well.

Hi Martin!! Lovely to hear your voice! I am showing this clip to my students tomorrow during our 'live lesson'. Hope you are well.
That was extremely concise and quick to the point! I enjoyed every second. You earned a subscriber.
This is a brilliant and simple video that helped me a lot with my common entrance practise, thank you! 😄👍🏻
finally someone that can explain science on youtube thank you
Thank you sir My daughter doing this project to her she helped this activity
This helped me so much for my practical thank you :)
Thanks for this, it honestly couldn't have been more simply helpful
Thanks you really helped me with my homework!!!!!!!!!!!!!!!!!
Lol same!
OMG! me too!...CHEM HW
pls reply
@@pathexe13 I got u
Every one of us has The same homework?
Oh man thank you very much man...its because of you that i was able to do my homework thank you.☺😊😀
Short but very brief! Thanks
thank you!!!!!!!!!!
you made my exam good for me!!!!!!
best man !!!!!!!
I left st pauls 2 years ago but your still helping me with chemistry now. Cheers Mr Godber thanks for the help
Glad I could help!
Thanks a lot for the explanation
I need this explanation for the test
iron + copper sulphate ------> copper + iron sulphate
A displacement reaction occurs since carbon is more reactive than iron, you can check in the Reactivity Series.
Symbol equation:
Fe + CuSO4 ------> FeSO4 + Cu
It's because Iron is more reactive than Copper. There's no Carbon involved.
@@martingodber3907 He means to say in the reactivity series Copper (Cu)is more reactive than Iron (Fe)but still it displace copper, why?
@@sakshiankur4607 no. Iron is more reactive than copper.
@@martingodber3907 Yes you are absolutely right, I just told you what this men wants to say. That's it
Thanks! Really helpful vid.
Your video was really helpful for me
Nice explanation sir,kindly upload more videos to elaborate chemical reaction
Sir you tell v.v good. This is the best video for this reaction
Thanks so much!! Science made easy 😁
Interesting and helpful
THANKYOU SOOO MUCH!!! IT REALLY HELPED - IT HELPED A LOT. THANKS KEEP IT UP!!!
Martin great work
so interesting, we learn new things everyday
Your video was really helpful for me ❤
Wonderful. Thanks 😊
anyone here after they have homework on this or their online teacher sent it
yah
i missed the demonstration she did on zoom so im using this video lol
Thank you sooo much sir!😮😮😮
thanks alot
helped with my exam
Thanks for my exhibition
cheers mate really helped
Thanks a lot!❤️
wowwww it was amazing!!!
Thank you :-)
This video is really super duper cool. One day I hope i can preform a medical procedure such as this
wow ur so cool
no you
Who is here 4 homework?

Hiya
Thank you sir...
VERY COOL
THANK FOR THE COOL NAIL :[]
Helped me with my prep!!
Good 👍
Please make more videos of chemistry's experiments
Very nice video
The explanation was perfect.plzz make other videos plzz.
Glad it made sense. Hope to be back in my lab in September!
so Fe + CuSO4 ====> FeSO4 + Cu
yeah basically
@@tenzonium Nothing happens in FeSO4 + Cu
Copper is less reactive, so the aqueous solution won't work.

love your accent
How do you get such a shiny copper layer? When I perform this test I get a lustreless brown collor :(
Hello Mr! I'm doing a copper sulfate aluminium copper battery! Do you have any recommendations on how I should handle a copper sulfate solution?
what would be the effect on heating the ferrous sulfate then? Thanks in advance
Good vid

Can u tell me the texture of copper displaced?
Like, does it form a rough and granular surface or is it flaky?
thank you
Nice vid
thnx
can stainless stick also work at this reaction ?
as i could not hear the video i searched it on youtube and i am here
That kind of looks like cool-aid. Anyways thanks for the help on the homework
Who else are watching this when their teacher shown them in class
very cool
Glad you like it. It's a great bit of chemistry!
this explanation is best....u saved the day...

So iron is more reactive when it comes to acid than copper right?
Absolutely. Iron is more reactive than Copper generally. Acids, Oxygen etc.
Thank s

Nice, Thanks
is anyone not watching this for homework? some people actually do this at home.
im using zinc instead of iron to make zinc sulfate for electroplating motorcycle parts. and see how it compares to a vinegar + Epsom salt solution.

How will the copper sulfate solution changes its colour to green?
susan wurangu - The Iron displaces the Copper to form Iron Sulphate (a green chemical) in solution. The Copper Sulphate has not turned green. It has reacted to form a new compound.
Hi! I was wondering if this is a chemical change or a physical change.
Definitely a chemical change - New substances are formed - Rearrangement/re-bonding of constituent atoms
What molarity should someone use when making the solution?
I did not use a pre-made solution. A couple of spatulas full in 100ml water gave a nicely coloured solution. Estimating the mass to be about 5g this equates to a 0.2M solution.
Can we crystalize this few04 solution to form ferrous sulphate crystals
Yes - But evaporate gently (without Bunsen if you have time). The pale green crystals can easily lose their water of crystallisation to become brown anhydrous Iron II Sulphate and if heated further this may release Sulphur Trioxide (white acidic fumes - very dangerous by inhalation) and reddish brown Iron III Sulphate
Is the product (iron sulfate) ferrous sulfate or ferric sulfate? (I'm guessing it's ferrous sulfate, no?)
It's Iron (II) Sulphate (Ferrous) - Hence the distinctive green colour.
Sir brown layer is cu or Fe??????
Copper. The Copper is displaced from the Copper Sulphate by the (more reactive) Iron.
Keep sending
What is the colour of the copper after displacement reaction?
Pink initially but brown (almost black) as a large deposit builds up.
M in class 7, so helpful
😀 understood in only 1 min
Glad it helped!
mm that blue rasperry sprite look tasty
So, if you placed aluminium in a copper sulfate solution, would the aluminium displace the copper as well?
+Mr.chang cooler Yes it would.
Martin Godber Even with its oxide layer?
+Mr.chang cooler Indeed! In fact, I often use a drop or two of Copper Sulphate solution to get aluminium/acid reactions going as they are impeded by the aluminium oxide layer.

Long answer :
Short answer : congratulations you got a molten iron and copper sulphate reincarnat as a iron sulphate and becomes green
