Question: In electrolysis, what happens to the ions in the electrolyte?

Options:

Correct Answer: They are oxidized or reduced at the electrodes.

Solution:

During electrolysis, ions in the electrolyte are oxidized or reduced at the electrodes, leading to chemical changes.

In electrolysis, what happens to the ions in the electrolyte?

Step 1: Electrolysis involves passing an electric current through a liquid called an electrolyte.
Step 2: The electrolyte contains ions, which are charged particles.
Step 3: When the electric current flows, the ions move towards the electrodes (the positive and negative terminals).
Step 4: Positive ions (cations) move towards the negative electrode (cathode) and gain electrons (reduction).
Step 5: Negative ions (anions) move towards the positive electrode (anode) and lose electrons (oxidation).
Step 6: This movement and change of electrons cause chemical reactions to occur at the electrodes.

Electrolysis – The process in which electrical energy is used to drive a non-spontaneous chemical reaction, involving the movement and transformation of ions.
Ions in Electrolyte – Ions in the electrolyte migrate towards the electrodes where they undergo oxidation or reduction.
Electrodes – Conductive materials where oxidation (anode) and reduction (cathode) reactions occur during electrolysis.
