What is electrolysis?
What is electrolysis?
Is the process by which ionic substances are decomposed(broken down into simpler substances when an electric current is passed through them.
In Electrolysis what move?
Ions move not electrons.
When does water reach its boiling point?
212 F or 100 C
What attracts the anode?
Cations are attracted to the cathode, while anions attracted to the anode.
What is reduction?
Reaction in which electron are added to a compound.
Why is ice melting a physical change?
When it happens the ice is still made water H2O molecules. It doesn't turn into a new substance.
When do we use electrolysis?
List them
Extraction
Purification of metals and compounds
Deposition of metals from solution(electroplating)
What happened during electrolysis?
Energy from electricity is being broken down.
Why is potassium more reactive than hydrogen?
Because hydrogen is lower than potassium on the reactivity series.
What are the industrial applications of electrolysis?
Extraction of metals
Purification of Metals
Electroplating of metals
What happens in oxidation?
When it goes to the anode it will lose an electron to form a gas except hydrogen.
