Hello, I have a question about the galvanic cell. It's typically made with a zinc electrode and a copper electrode. Could I, for example, simply replace the zinc with lead, and the processes within the cell would be the same, just with lead instead of zinc?

Loading...Hello, I have my advanced chemistry exam coming up soon and wanted to ask, since my teacher explained it in a somewhat complicated way, which inter- and intermolecular interactions hold the individual structural planes together. In the alpha helix, it should actually be hydrogen bonds, but my teacher's slides also mention Van der Waals bonds,…
Hi In the reaction of chlorine and lithium I get 2 Li(+) + 2Cl(-) How do I write this together now because sometimes my teacher writes that as LiCl but with e.g. Al + Cu (2+) you get 2Al(3+) + 3Cu and you just leave it like that? So when do I omit a plus?…
Hello, Is the dye brilliant black in the short or long wavelength range of the spectrum?
What if you heat the chlorinated water with fire, for example?
Calculate the volume of carbon dioxide a plant needs to synthesize 150g of glucose? I don't understand this problem.
Good day dear people I still have some work to do on the Daniell cell, and I have an exam on it tomorrow. Unfortunately, I don't understand the problems and urgently need help from someone. The Daniell cell in this experiment is constructed with a copper and zinc sheet. Between each sheet are two gels:…
Not quite. Suppose you always have standard cells and standard conditions, you can tap a voltage of about 1.1 V from the zinc and copper galvanic element. If you now replace zinc by lead, it is only approx. 0.5 V. This is because the standard potential of lead is significantly higher than that of zinc.
Oxidation and reduction still proceed analogously. So copper is reduced and lead or Zinc oxidized.
That’s what I thought about the tension. I was more concerned with all the steps. Thank you!
What is oxidized and reduced can be read from the voltage series.
Practically, this may still work a bit different, but for theory it is enough.
