Explain why the electrolyte has to be a liquid.

• So the ions can move

• So the electrons can move

• So that it doesn't get too hot

• So the fish are ok

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

• Breaking apart

• Losing electrons

• Clumping together.

• Gaining electrons

In an aqueous solution of copper chloride, which ions are attracted to the negative electrode?

• Cu²⁺ and Cl^- and H⁺ and OH^-

• Cu²⁺ and H⁺ 

•  Cl^- and OH^-

• Cu²⁺ 

An ion is

• Also a compound

• An atom that has gained or lost an electron

• An atom that has only gained electrons

• An atom where the number of protons=electrons

Anions

• Gain electrons, has an overall positive charge

• Lose electrons, has an overall positive charge

• Lose electrons, has an overall negative charge

• Gain electrons, has an overall negative charge

What is the charge of an anion?

• Positive

• Negative

• Neutral

• Variable
