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

  • $\begingroup$ Also, Ag might migrate into the copper electrode... Hg certainly does. $\endgroup$ – DrMoishe Pippik Mar 28 '17 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? $\endgroup$ – Kieren Albuquerque Mar 30 '17 at 1:02
