i have a solution of silver nitrate at 1M. the aim of my experiment is to determine in 40 mins, how much Ag will be deposited. Should i use copper or graphite electrodes.

$\begingroup$ How much will deposit? Nothing. You forgot to turn on the current. $\endgroup$– Ivan NeretinMar 28, 2017 at 11:16

I'd suggest you do it with graphite electrodes.
Because:
- Its more inert than copper
- If copper is used, it readily reacts and more copper will be deposited at the cathode compared to silver
- the yield of silver will be greatly reduced

$\begingroup$ Also, Ag might migrate into the copper electrode... Hg certainly does. $\endgroup$ Mar 28, 2017 at 23:18

$\begingroup$ Also, If i have a solution of AgNO3 (is diluted with water), what will oxidise and what will reduce. What are the half reactions? $\endgroup$ Mar 30, 2017 at 1:02
