The diagram illustrates the electrolysis of a mixture containing aqueous copper(II) nitrate, $\text{Cu(NO}_3)_2\text{(aq)}$, together with aqueous silver nitrate, $\text{AgNO}_3\text{(aq)}$. Electrodes X and Y are inert. Copper is above silver in the reactivity series. It follows that ……1…… is first deposited at electrode ……2……. Which words correctly fill gaps 1 and 2?
- Acopper, X
- Bcopper, Y
- Csilver, X
- Dsilver, Y
