Silver Nitrate Electrolysis 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.
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
