4 cards from this section. Quick, good the night before a test.
What does electrolysis use to drive a chemical reaction?
Think about what is needed to initiate non-spontaneous reactions.
What is Faraday's First Law?
It relates mass to electricity.
What is the primary driving force of electrolysis?
Consider what is used to initiate the process.
True or False: Faraday's Second Law states that the same quantity of charge will always produce the same mass of products in different reactions.
Think about how different substances may behave.
Calculate the amount of aluminum deposited when a 15 A current is passed for 25 minutes through an aqueous aluminum sulfate solution.
Don't forget that aluminum requires 3 moles of electrons to deposit 1 mole.
Determine the volume of hydrogen gas produced at STP from the electrolysis of water using a 4 A current flowing for 2 hours.
Water decomposition requires 2 moles of electrons per mole of hydrogen produced.
