Purifying Copper by Cara Enright https://padlet.com/enrightcara9/xr1jd4yzmlsq en-us 2018-02-08 22:47:31 UTC 2025-11-01 23:48:58 UTC hello@padlet.com Emily https://padlet.com/enrightcara9/xr1jd4yzmlsq/wish/229987779 - The electrodes are made of copper
- Oxidation occurs at the anode
-Reduction occurs at the Cathode
- Impure copper at the anode
-Pure copper at the cathode]]> 2018-02-09 12:41:56 UTC https://padlet.com/enrightcara9/xr1jd4yzmlsq/wish/229987779 Charlotte https://padlet.com/enrightcara9/xr1jd4yzmlsq/wish/229987839 Anode is made of impure copper

The electrolyte is s copper sulphate solution
The ions in the solution are Cu+ and SO42-
At the anode oxidation occurs 
The half equation at the anode=Cu to Cu++2e-
The half equation at the cathode=Cu2++2e- to Cu
Anode loses mass]]> 2018-02-09 12:43:00 UTC https://padlet.com/enrightcara9/xr1jd4yzmlsq/wish/229988049 Olivia https://padlet.com/enrightcara9/xr1jd4yzmlsq/wish/229988124 The electrolyte is copper sulphate solution
Impurities sink to the bottom

Copper sulphate solution
Copper ions leave the anode and are attracted to the cathode where they are deposited as copper atoms
