Unit 1- Electrolysis Flashcards
What is electrolysis?
The flow if ions through solutions and molten compounds
What is an electric current?
The flow of charged particles
What are electrolytes?
Conducting solutions an molten compounds
What does electrolysis do?
Chemically charges the electrolytes and it may led to the break up of compounds
Is the electricity supply a.c. Or d.c.?
D.c.
Why does the supply have to be d.c.?
So that the product so electrolysis can be identified
What does OIL stand for?
Oxidation Is Lose
What does OIL mean?
The negative non-metal ions lose electrons at the positive electrode
What is the positive electrode called?
The anode
What does RIG stand for?
Reduction Is Gain
What does RIG mean?
The positive metals gain electrons at the negative electrode
What is the negative electrode called?
The cathode
What happens at the cathode in electrolysis?
The migration of coloured ions
What happens at the anode in electrolysis?
Effervescence
