Question

why do the aluminum ions move to the negative electrode ? what happens to them there ?​

Answer 1

Positively charged ions move to the negative electrode during electrolysis. They receive electrons and are reduced . They lose electrons and are oxidised . The substance that is broken down is called the electrolyte.

The ions in the aluminium oxide must be free to move so that electricity can pass through it. ... positively charged aluminium ions gain electrons from the cathode, and form molten aluminium. oxide ions lose electrons at the anode, and form oxygen molecules.

Answer 2

The aluminum ions move to the negative electrode because:

• Just as electric current is transmitted across ionic compounds, they are decomposed (broken down).
• The movement of electrons or ions is stated as electricity. The substance must possess ions in order for electrolysis to function. Because they include neutral atoms, covalent molecules cannot behave as electrolytes.
• The ions have to be able to travel freely, which is achieved when an ionic material is dissolved in water or melted.
• During electrolysis, the following happens:

1. During electrolysis, positively charged ions travel towards the negative terminal. They are decreased after receiving electrons.
2. During electrolysis, negatively permeated ions travel towards the positive terminal. They are oxidised as they lose electrons. The electrolyte is the material that is broken down.
