C6 Electrolysis Flashcards
What is electrolysis?
Electrolysis is a chemical process that uses electricity to induce a chemical reaction, often to separate elements from their compounds.
True or False: Electrolysis can be used to purify metals.
True
What are the two electrodes used in electrolysis called?
Anode and Cathode
Fill in the blank: The process of electrolysis requires a __________ to conduct electricity.
Electrolyte
What is the role of the anode in electrolysis?
The anode is the electrode where oxidation occurs.
What happens at the cathode during electrolysis?
Reduction occurs at the cathode.
True or False: Electrolysis can only occur in liquid solutions.
False
What type of reaction occurs at the anode during the electrolysis of water?
Oxidation reaction
What is the main product of electrolysis of water?
Hydrogen and Oxygen gases
What is a common use of electrolysis in the industry?
Electroplating
True or False: Electrolysis can be used for the production of chlorine gas.
True
What is the effect of increasing the concentration of an electrolyte on the rate of electrolysis?
It generally increases the rate of electrolysis.
What is Faraday’s first law of electrolysis?
The mass of a substance produced at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte.
Fill in the blank: The process of electrolysis can also be described as __________ of ionic compounds.
Decomposition
