4 cards from this section. Quick, good the night before a test.
What is the first law of Faraday?
Think about how mass and electricity are related.
What is the formula for calculating charge (Q)?
Remember, charge comes from current times time.
What law states that mass produced is proportional to charge passed?
Think about the relationship between mass and electricity.
True or False: The second law of Faraday states that all substances produce the same mass under the same current.
Consider the different identities of substances.
If a solution of silver nitrate (AgNO₃) undergoes electrolysis with a current of 4 A for 1500 seconds, how much silver (Ag) is produced? Use the half-equation Ag⁺ + e⁻ → Ag. Include all steps.
Don't forget to convert current time to charge to get started.
Consider an electrolytic cell converting water into hydrogen and oxygen using an external power source. If 1000 C of charge has been passed, how many moles of hydrogen gas are produced? Use the reactions: 2H₂O → 2H₂ + O₂ for reduction (for H₂) and 2H₂O → O₂ + 4H⁺ + 4e⁻ for oxidation (for O₂).
Relate the moles of electrons to the balanced half-reaction for hydrogen production.
