Which gas is produced during the electrolysis of water? (2020) 2020

Step 1: Understand what electrolysis is. It is a process that uses electricity to break down a substance.
Step 2: Know that water (H2O) is made of hydrogen and oxygen.
Step 3: During electrolysis, water is split into its two components: hydrogen and oxygen.
Step 4: Identify the two electrodes used in electrolysis: the anode and the cathode.
Step 5: At the anode (the positive electrode), oxygen gas is produced.
Step 6: At the cathode (the negative electrode), hydrogen gas is produced.
Step 7: Conclude that the gas produced at the anode during the electrolysis of water is oxygen.
