Calculate the electrode potential for a silver filled electrode in a solution of 0.00550 M AgNO3 solution.
I feel like I need the nernst equation for this but if not, can somebody show me the way? Thank you!

using equations, explain each of the observations made at each electrode in part A....
These were our results for this experiment:
solution | pH+ | observation at cathode | observation at anode | anode |
NaCl | Base | A lot of bubbles | a little bit of bubbles | acid |
NaBr | base | a lot of bubbles | tiny bubbles and it turned pae yellow | neautral |
NaI | base | little bit of bubbles | turned dark yellow | base |
AgNO3 | acid | bubbles/ shiny silver | no change | neutral |
CuSO4 (c electrode) | acid | red copper @tip | bubbling | acidic |
CuSO4 (Cu electrode) | acid | lighter at electrode | darkter at electrode | acidic |
This is what we used during our experiemnt:
experiment | solution | electrodes |
1 | 0.1 M NaCl | graphite |
2 | 0.1 M NaBr | graphite |
3 | 0.1 M NaI | graphite |
4 | 0.1 M AgNO3 | graphite |
5 | 0.1 M CuSO4 | graphite |
6 | 0.1 M CuSO4 | copper |
we used a u-tube for this experiment and inserted electrodes in each side
This is a post lab question and I need help writing equations for observations made at each electrode, thank you
