electrochemistry - galvanic cell consutrction
« on: March 25, 2024, 08:46:41 AM »
I'm trying to make a galvanic cell using 0.25M of lead(II) nitrate and 1M of iron(II) sulfate. What I don't understand is how to get the half reactions and the standard reduction potential of the lead nitrate

all I figured out was the lead is reduction cathode: Pb2+ --> Pb

 and iron is the oxidation anode: Fe3+ --> Fe2+

Do you know the Nernst equation.
The Standard Potentials are listed in a table.

https://en.m.wikipedia.org/wiki/Standard_electrode_potential_(data_page)

Fill it in and use also the concentration.
