Question: What is the primary product of the electrolysis of aqueous NaCl?

Options:

Correct Answer: Chlorine gas

Solution:

During the electrolysis of aqueous NaCl, chlorine gas is produced at the anode due to the oxidation of chloride ions.

What is the primary product of the electrolysis of aqueous NaCl?

What is the primary product of the electrolysis of aqueous NaCl?

Step 1: Understand that electrolysis is a process that uses electricity to break down a substance.
Step 2: Know that aqueous NaCl means salt (sodium chloride) is dissolved in water.
Step 3: Identify the two electrodes used in electrolysis: the anode (positive electrode) and the cathode (negative electrode).
Step 4: At the anode, chloride ions (Cl-) from the NaCl solution are oxidized, meaning they lose electrons.
Step 5: When chloride ions lose electrons, they form chlorine gas (Cl2).
Step 6: Therefore, the primary product at the anode during the electrolysis of aqueous NaCl is chlorine gas.
