because it's wrong XD, those ions must be already in the solution, either leaving copper oxidize in sulfuric acid on it's own or charging the battery or pouring copper sulfate in the solution which is already oxidized, otherwise copper will not oxidize easily if connected with the more basic(zinc sulfate) solution so copper atoms are not going to abandon the metal surface easily they will rather make zinc oxidize faster. For the discharging reaction to occur you must have zinc metal oxidizing in an acid and copper ions reducing to go back copper metal

A salt bridge can be any solution that is able to harmonize the two solutions. KNO3 is just an example.

no problem, id been having trouble with this and redox reactions in general and text books can be confusing. This video helps a lot.

Love your videos!!!! Please keep up the good work! Best regards!

Well, it's a little bit tricky because I explained it the "soft" way. In fact, the salt bridge also transfers ions from one pot to the other. So, there is an exchange between: a) salt bridge AND left pot, b) salt bridge AND right pot, and left pot AND right pot.

Thank you very much :)

Perhaps in the future, yes.

Nice video , looking forward for more of such videos

Best explanation I found after spending soo much time looking. Other videos don't explain the role of the salt bridge. They also make it sound like copper won't release ions in aqueous solutions. Like there's some fundamental difference between copper and zink in that regard.

Very nice explanation, cheers!

I dont understand how positive ions can go to the B side (cathode), when the electrons from A side go there, but they can't just return to A side. You would probably say because of the oxidation. But this oxidation happens on both sides. Does anyone has idea?

Thank you! This is so clear.....

2:10 I'm confused by Oxidation. If both rods are initially uncharged and the zinc/copper in the solution are positively charged, then why wouldn't the electrons flow into the solution? Why do the atoms move into the solution as positive ions (positive into positive) and leave electrons on the rod? 2:45 If both rods are gaining electrons, then why does the zinc become positively charged and the copper negatively charged? Shouldn't both gain a negative charge, but the zinc would gain it faster? I'm still confused by this process

@SreenivasuluTadakaluruStephen

+maxpowers3732 I think this is the reason, as you doubted Cu too can lose electrons. But in this case Zn loses electrons easily than Cu. So released electrons from Zn travel to Cu plate(electrode. Then Cu plate becomes negatively charged. As you know negatively charged Cu plate attract positive ions. Look at the electron configuration of Cu and Zn. For Zn it is easy to lose 2 electrons but in Cu to become Cu2+ ion i have to 1 d-electron from inner shell. Cu:[Ar] 3d10 4s1 Zn: [Ar] 3d10 4s2 or other way, Zn can achieves more stability than Cu due to fully filled d-orbital by losing 2 valence electrons. Cu:[Ar] 3d9 4s2 Zn: [Ar] 3d10 4s2

Because ions must travel from one pot to another. If not, there will be an imbalance. It's clear if you watch the animation closely.

What if the solutions I will use are different? For example hydroxhloric acid Help pls asap

You're welcome :)

Well explaination

can you explain the salt bridge working and significance a little more elaborate ..if possible?

So the difference in potential is due to the different number of electrons in both electrodes ?

well explained

Man thank you so much 😊😊😊😊😊😊

Thanks man :D really helpfull

very nice

Awesome

If both electrodes are becoming negatively charged, it seems misleading that both start at 50, and the zinc climbs to 80, and the copper lowers to 20. Would it not be more appropriate to raise the zinc from 50 and raise the zinc to a higher number?

2:14 Okey, zinc is reactive, but I still can't understand what causes zinc to lose electrons if the solution is uncharged. Will the mere presence of sulfate ions around the metallic zinc induce the ionization?

Thank you

At 2:38 - 2:43, can anyone explain when CU metal lose electrons at a much slower rate than Zn, why Zn still lose electrons to CU? I thought electrons usually flow to areas when it has fewer electrons?

Thanks for the explanation, but can anyone please explain to me how the flow of charges is maintained after the Cu ions are pulled to the Cu electrode and the electrode hence becomes neutral?

a salt bridge is used

its vry use full for study......

why can't electron pass thru the salt bridge? why can't you form a battery with copper and zinc touching each other? why doesn't zinc atom donate the electron to the H+ and form H2, why does it flow thru the circuit? Why doesn't zinc atom donate e to the H+ and form H2 WITHOUT any closed circuit? why do you need a salt bridge at all? why can't you just have 2 solutions mixed together? if it is indeed the magic of the salt bridge, what about a lead acid battery? Why doesn't any KZread video comes close to explain those questions? have any video maker thought thru the entire process at all?

I could not understand why the anode is negative when its give out electrons to the other electrode ?

now get it✌ tnxx

Hai,Thanks for the video.It was helpful. I have a doubt regarding this by the way.I understand that salt bridge is Na2SO4 salt.When Oxidation happens, Zinc atom loses its 2 electron which goes to the external circuit and zn2+ ion will be in the zinc sulphate solution.Zinc ion reacts with SO4 2- ions from the salt bridge and the electrolyte would be neutral.Now in the cathode part Copper from copper sulphate solution combines with the 2 electrons from the anode and copper metal deposites on the cathode leaving soa 2- ions.This makes the electrolyte at cathode negative in charge. 1.What happens to SO4 2- ions,does it combine with Na2+ ions in the salt bridge turning the solution a mixture of Na2SO4 and Cu2SO4 solution? 2.Untill what condition does the redox reaction prolong,Is it untill zinc totally gets consumed or at a condition where there is no more Na2+ or SO4 2- ions in Salt bridge to balance the electolytes?

Sir, you cleared doubt

If the solution in the salt bridge is used for balancing the two reservoirs, why is the bridged connection required at all? Why not just have two disconnected tubes? Please help. I've been trying to wrap my head around the salt bridge for days now. No one I've talked to has any answers...

2:46 at this copper 2+ ion gets deposited on cathode but what are you showing in not true.

why did both zinc and copper became ions when placed in the solution and left their electrons on the electrodes?

You messed up. You show the Positive copper ions leaving their electrons in the electrode and becoming part of the copper sulfate solution. the electrons are pulled from the electrode by the sulfate creating negative ions in the electroe not the electrolyte. this creates a potential energy as the electrons left in the zinc electrode create a current that fills the positively charged copper ions in the copper electrode. The electrons expelled from the copper electrode (in a battery) pass through the membrane to neutralize the zinc negative ions

Nice intro music 😂✌️

Every other person understood the video... Perhaps you should check Wikipedia or another website.

Why do we need a Salt Bridge if Electrons can travel through a copper wire?

The anode is the negative TERMINAL, meaning the electrons flow from the anode (zinc) to the cathode(copper). The Anode is negative because the electrons stay in the zinc strip and later flow to the cathode, while the zinc atoms from where the electrons are released from jump INTO the solution and become ions. So basically, only the electrons and the normal atoms of zinc remain in the anode while the atoms that become positive LEAVE the anode.

I don't understand why zinc can lose its electrons even if it is in ZINC sulphate solution? I mean the zinc atoms in the anode and the zinc ions in the solution are both zinc!

Because here to metallic pressure is greater than osmotic pressure so to balance we increase osmotic pressure by increasing concentration in solutions. To increase concentration of solution add ions.
