In electrolysis, what is produced at the cathode?

In electrolysis, what is produced at the cathode?

Step 1: Understand what electrolysis is. It is a process that uses electricity to break down a substance into its components.
Step 2: Identify the substance being electrolyzed. In this case, we are looking at water (H2O).
Step 3: Know the two electrodes involved in electrolysis: the anode (positive) and the cathode (negative).
Step 4: During electrolysis of water, the cathode is where reduction occurs, meaning that electrons are gained.
Step 5: At the cathode, water molecules gain electrons and are converted into hydrogen gas (H2).
Step 6: Therefore, the product at the cathode during the electrolysis of water is hydrogen gas.
