electrode A conductor used to establish electrical contact with a circuit. The electrode attached to the negative terminal of a battery is called a negative electrode, or cathode. The electrode attached to the positive terminal of a battery is the positive electrode, or anode. cathode The negative electrode during electrolysis.
Electrolysis needs: dc Direct current. electrode A conductor used to establish electrical contact with a circuit. The electrode attached to the negative terminal of a battery is called a negative electrode, or cathode. The electrode attached to the positive terminal of a battery is the positive electrode, or anode.
The electrode attached to the positive terminal of a battery is the positive electrode, or anode. cathode The negative electrode during electrolysis. anode The positive electrode during electrolysis. During electrolysis: cation An atom or group of atoms that have lost electrons and become positively charged.
The positive electrode, on the other hand, will attract negative ions (anions) toward itself. This electrode can accept electrons from those negative ions or other species in the solution and hence behaves as an oxidizing agent. In any electrochemical cell the anode is the electrode at which oxidation occurs.
In any electrochemical cell (electrolytic or galvanic) the electrode at which reduction occurs is called the cathode. The positive electrode, on the other hand, will attract negative ions (anions) toward itself. This electrode can accept electrons from those negative ions or other species in the solution and hence behaves as an oxidizing agent.
anode Positively charged electrode. Molten lead bromide, PbBr 2 (l), is an electrolyte. During electrolysis: Lead forms at the negative electrode and bromine forms at the positive electrode. At the cathode: Pb 2+ + 2e - → Pb At the anode: 2Br - → Br 2 + 2e -
