electrolysis-1

What does electrolysis mean

Splitting up with electricity

What is an electrolyte

A liquid or solution that contains an ionic compound (ions in a electrolyte are free to move)

What is an electrode

What are the two electrodes?

A solid conductor (metal ore carbon)

On the right there is a positive electrode called the anode on the left. There is a negative electrode called the cathode

What do you join electrodes with and why

With a wide so the electrons can flow between them. Then you need a power supply to drive the flow of electrons

How does electrolysis work

in electrolysis the electrodes are placed into the electrolyte in beaker and ions move from one electrode to the other. This allows the conduction of electricity through the circuit. The positive ions in the electrolyte will move towards the negative electrode (the cathode) and gain electrons the negative ions in the electrolyte will move towards the positive electrode (the anode) and lose electrons as ions gain or lose electrons. They become atoms or molecules and are released. These atoms or molecules are the products of electrolysis.

Why is electrolysis not used to extract all metals?

Because electrolysis requires a lot of energy making it very expensive

What happens to positive ions during electrolysis and to negative ions

1. They are attracted to the cathode (negative electrode).

2. They gain electrons.

This means they have been reduced.

Negative ions

Are attracted to the anode

They lose electrons

This means they are oxidised

Why can't ionic solids be electrolysed?

Ions are not free to move

Why can molten ionic compounds be electrolysed?

so ions are free to move

Describe the electrolysis of Milton ionic substance(metals

During the electrolysis of the substances that metal ions move to the cathode and gain electrons to become neutral while the non-metal ions move to anode to lose electrons to become neutral
