text: i need help finding info on the electrolysis of zn and cu in an nano3 solution?   the nano3 is just a solution used to ionize the metals, assuming you are using a dry cell battery. if not, such as a half-cell reaction, the cu would be reduced due to its higher seating on the reactivity series and the zn would be oxidized. for more info check out, www.chemistry.co.nz /redox_begin.htm it works great.
