Question

How do you solve for # of electrons transferred? # of Cu atoms oxidized at an anode? # of Cu atoms reduced at cathode?
data given:

number using electrolysis, 2204 a2040 153-1 Mas of 54, 729 f 131.5 2- Mass ofeopper cathode 3. Initial current reading 2.5 2.LI Final current reading 5. Average current 3.15 3.15 3.15 reading 6. Time for run in seconds Las 18bit 1326 Final mass of anode zo. 2 26 l, 5 138. 8. Final mass of cathode 9 Mass loss of anode 5.4 31.7 19 lo Mass gained by cathode 11. Moles of Cu kost by anode 12, Moles of Cu gained by cathode 2L12. .205 13. Coulombs used

Explanation / Answer

It is easy to understand that the mass of copper anode is decreasing which indicated that at anode copper is oxidising and the mass of copper cathode is continiously increasing which meams at cathode copper reduces and deposit at cathode. As the result mass of cathode rod increasing .
