The diagram shows the electrolysis of a mixture of aqueous copper(II) nitrate, Cu(NO3)2(aq), and aqueous silver nitrate, AgNO3(aq). Electrodes X and Y are inert. [diagram of electrolysis cell with electrodes X (+) and Y (−) in a mixture of AgNO3(aq) and Cu(NO3)2(aq)] Copper is above silver in the reactivity series. It can be deduced that ......1...... is initially deposited at electrode ......2...... . Which words correctly complete gaps 1 and 2?

1. Acopper X
2. Bcopper Y
