Which of the following will be applied when a metal Y is used to electroplate another metal X in electrolysis?
X is the anode and very high current is used
X is the anode and Y is the cathode
Y is the cathode and X is the anode
Y is the anode and very high current is used
Vysvětlení
Metals and hydrogen are deposited at the cathode, while non-metals and oxygen are deposited on the anode
∴ metals Y will form the anode which is deposited at the cathode made of x
∴ metals Y will form the anode which is deposited at the cathode made of x
