What is electrolysis?
Electrolysis is the process of using light to drive a chemical reaction.
Electrolysis is the process of using heat to drive a chemical reaction.
Electrolysis is the process of using a magnetic field to drive a chemical reaction.
Electrolysis is the process of using an electric current to drive a non-spontaneous chemical reaction.
What are the two electrodes used in electrolysis called?
anode and cathode
cathode and anode
positive and negative
north and south
Which process occurs at the anode during electrolysis?
Reduction
Oxidation
Condensation
Evaporation
Which process occurs at the cathode during electrolysis?
Condensation
Reduction
Evaporation
Oxidation
What is the purpose of adding an electrolyte to the solution during electrolysis?
Facilitates the flow of electric current
Causes the solution to evaporate faster
Reduces the conductivity of the solution
Increases the temperature of the solution
What is the chemical equation for the electrolysis of water?
H2O(l) -> H2(g) + O2(g)
2H2O(l) -> 2H2(g) + O2(g)
2H2O(l) -> H2(g) + 2O(g)
H2O(l) -> H2(g) + O(g)
What is the product of the electrolysis of molten sodium chloride?
Sodium hydroxide and hydrogen gas
Sodium metal and chlorine gas
Sodium hydroxide and chlorine gas
Sodium chloride and water
What is the product of the electrolysis of aqueous copper(II) sulfate?
Copper metal (Cu)
Copper oxide (CuO)
Sulfuric acid (H2SO4)
Oxygen gas (O2)
What is the role of electrons in the process of electrolysis?
Electrons are released as a byproduct
Electrons flow through the external circuit, balancing charge and facilitating redox reactions.
Electrons are consumed during the process
Electrons have no role in electrolysis
How is the amount of substance produced during electrolysis related to the current and time?
The amount of substance produced during electrolysis is only related to the current, not time.
The amount of substance produced during electrolysis is not affected by either current or time.
The amount of substance produced during electrolysis is directly proportional to the current and time.
The amount of substance produced during electrolysis is inversely proportional to the current and time.
