Galvanic Cells (Voltaic Cells)

Published on August 14, 2015 by

All about Galvanic Cells, which are also called Voltaic Cells. These are devices that use a chemical reaction to create electricity. Moving electrons create electricity, and electrons flow from the anode, the site of oxidation, to the cathode, the site of reduction. The galvanic or voltaic cell also includes a salt bridge, which helps to balance charge, and lets ions move between the two half cells. In this video, we'll talk about oxidation, reduction, cathodes, and anodes. We'll write redox half reactions for the two half cells, which show the gain and loss of electrons.

    Question have you ever attempted to take a Baltic dry cell can connect the I believe anode to ground and the cathode high up into the atmosphere or very least a huge or long Tesla coil of copper up in the air there’s a theory that connecting able to pick up dry pile to Earth and the sky you can have a constant flow of electricity

    I just came across this video…..thank you for at last I understand 90% of how a battery works….2 points please…1) dont the electrons from the zinc push other electrons in the wire rather than flow though? and 2) is there a short explanation why its called reduction and not addition? reduction to me complicates as the copper adds atoms to its mass

    An excellent video, as always.
    There’s something I don’t get though, and it may sound stupid, but does the redox reaction happen only when the electrodes are connected? Or are the zinc atoms already becoming ions and vice versa for the copper ions before they are connected?
    I can’t wrap my head around this. Help!

    so basically, copper is a highschool bully stealing lunch from weaklings like Zn

    • Azaan Khan 2 years ago

      it’s similar to displacement, but that’s more of a mister-steal-your-girl kinda of a thing

    • kipper 2 years ago

      @Azaan Khan you ppl are wasting your time. Learn more about orbitals so that you can explain it in the exam and understand other similar problems. , bs about stealing boyfriends or lunch will get you nowhere.

    • Azaan Khan 2 years ago

      @kipper you misunderstand. we say stealing lunch or boyfriends, not as a way of explaining something, but it helps with understanding how the thing works, when trying to understand it and keep it in memory. Analogies too, sometimes, are explanations in themselves.

    what happen if the solution is just NaCl and the electrode are Zn and C? what is the reaction that happen in this case? in cathode and anode. please help me to solve this. actually i still confuse with reaction that appear in galvanic cell and electrolysis, is it same or not. i mean the reaction that happen in cathode and anode between galvanic cell and electrolysis. i read that in electrolysis we must to see what electrode we used for anode reaction (inert or not), are galvanic reaction use the same rules too?. thankyou

  • Autism Farmer 2 years ago

    Science is too confusing for me … reduction = an increase in mass (ouch) …. salt bridge causes an eventual and complete separation of sodium and chloride so that the cell can no longer function. (ouch) …… now if a voltaic cell were alive, then the excess sodium would simply be sweated out of the skin and the excess chloride would be excreted in the urine …. and the salt would be ingested continuously to feed this process endlessly …. so why don’t batteries urinate, sweat and be fed? oops, I also forgot the copper solution CU(aq) would eventually be depleted as well (yikes) … I wonder how to feed the copper solution? – Tyler, What new battery technology would you recommend that we research?

    Could you explain why exactly Zn has a weaker ‘pull of electrons’ than Cu^2+ ?

    • Abhishek Palakkal Kaliyath 2 years ago

      Not a reply to your question but prompts me to ask another question to author – Why does Cu^2+ not take electrons from Cu (solid) because I understand Cu is a good conductor of electricity as it has free moving electrons – Why go all the way round to Zn for electrons when you have it in your own backyard?

  • Ramiro Cubria 2 years ago

    This was the clearest explanation of the subject I’ve ever seen. FAR better than my teachers.

    how do we know that copper has a stronger pull than zinc? Like without that I don’t know how to identify the anode or cathode

  • Fresh Off the Milk 2 years ago

    How are you able to distinguish which element has a stronger pull for electrons

    • Mary Kate Murschell 2 years ago

      Fresh Off the Milk you can use the Standard Reduction Potentials table – it would be whichever has a higher value

    • Fresh Off the Milk 2 years ago

      Mary Kate Murschell thanks alot! So the higher value is the cathode, correct?

    • Mary Kate Murschell 2 years ago

      Fresh Off the Milk yup!

  • Nikan Rst 2 years ago

    Amazing demonstration. One question: At the start of the reaction, does the Cu2+ really sense the Zinc sitting there at the other end? Is that what triggers the process? Or is it because Z next to the solution of ZincSolphate prefers to lose its electron regardless of the presence of Cu++ at the other end? If the latter is true? Why is this?

    • Saumyojit Das 2 years ago

      as far i have understood zinc loses its electron due to pull of more electronegative element cu….so it is automatically potential difference is created right ??

  • Aedon Janes 2 years ago

    Bro thank you so much! You are the best. One thing though is when discussing Voltaic cells be careful of the electron flow. You put the arrows for electrons from Zinc to Copper without first discussing the anode and cathode. This could be misleading, as it is key to discover which is your anode and which is your cathode before writing the arrows.

  • Arshdeep Sahi 2 years ago

    God literally bless, i have a final tomorrow and u saved my ass

    What is the average amperage of a simple cell. Putting the zinc directly into cuso4 gives me the most amperage. Do I need to concentrate my cuso4? I only I get about 200 ma with couple inches of copper and zinc.

  • ajtemp2000 2 years ago

    All I hear is chemical reaction, chemical reaction, none of these are elements. If you can get “electrons” from a lemon what of the zinc and copper in a “sulfate solution”.

    Chemistry is all Chemicalsrty.
    Hardly any of these so-called elements” are naturally occurring, and are instead a manufacture product. go and see how Sodium is “made”.

    9. At the end of the experiment, the zinc electrode was coated in a black substance – most likely zinc oxide. Explain how this would affect the measurement of Avogadro’s number (specifically explain whether this would lead to an overestimate or an underestimate of Avogadro’s number, or have no effect, and explain why.)

    10. Zinc oxide is not conductive. If this ZnO layer were thick enough to affect the experiment, what would you expect the effect to be on the observed current throughout the course of the experiment? Was this effect observed in the data?

    11. Give one other source of error for which you could anticipate whether it would cause an overestimate or an underestimate in the calculated value of Avogadro’s number. Explain why it would lead to an over- or underestimate.

  • HeyHannah 2 years ago

    Can someone explain one thing:
    So at the end when he’s talking about the salt bridge to balance out charges, what’s the point of the salt bridge? Why can’t electrons just go “backwards” to Zn to balance out the charges?

    • Aliyanah Ramluckan 2 years ago

      I think its because no matter what , copper will always have a “greater pull” for electrons than the zinc. So it will never give electrons back to the zinc

    • HeyHannah 2 years ago

      Aliyanah Ramluckan ooooooh that makes a lot of sense thank you so much for replying!

    • Aliyanah Ramluckan 2 years ago

    • helinadaniel 2 years ago

      yap you are right

  • Patrick Betyounan 2 years ago

    I have two queries if anyone can answer. Firstly, why is the charge of both solutions important for electron transfer? Wouldn’t the balanced copper solution be sufficient enough to receive electrons from zinc if there were Cu2+ ions available? Secondly, I don’t understand why it has to be a bridge? Again this touches on the first point, however even if both solutions required balancing, can’t you just have two salt sticks in each beaker instead of a bridge? Wouldn’t the cl- still be attracted to the Zn2+? Or is it because the cl- will be depleted and then the NaCl would want to join the cl- hence it won’t be balanced anymore?

  • Nizar Chaleila 2 years ago

    But what happens after the copper ions are all gone? The Na ions will move in the solution with the copper and that fixes the charge inequality problem. But why would the zinc send out electrons through the wire anymore? It has no attraction to anything in the copper solution, it seems to me, so the electrons will stop travelling through the wire, thus ending electricity. The salt bridge, given this view-point, is useless. I know I am wrong, but what am I missing?
