Question

How do you remember at which electrode oxidation occurs and at which electrode reduction occurs?

Answer 1

In an electrochemical cell, oxidation occurs at the anode, and reduction occurs at the cathode. The mnemonic device 'OIL RIG' can help remember this.

Step-by-step explanation:

In an electrochemical cell, the electrode at which oxidation occurs is called the anode, while the electrode at which reduction occurs is called the cathode. The direction of electron flow is from the anode to the cathode. To remember this, you can use the mnemonic device 'OIL RIG' where OIL stands for 'Oxidation Is Loss' and RIG stands for 'Reduction Is Gain'.
