Positive ions (cations) will move towards the cathode (-) where they will discharge by....

• Breaking apart

• Losing electrons

• Clumping together.

• Gaining electrons

What is the equation to show what happens to Cl ions at the anode.

• Cl^- --> Cl + e-   

• 2Cl^- --> Cl₂ + 2e-   

• Cl₂ + 2e-   2Cl^- 

• Cl₂ + 2e-  _-->  2Cl^-

A positive ion is called a(n):

Why are ions attracted to each other?

• Cations and Anions have opposite charges.

• Cations think Anions are cool.

• The fact that both are metals allows them to mix.

• The ions change their electrons again.
