4 cards from this section. Quick, good the night before a test.
What is Faraday’s Second Law about?
Think about how electric charge affects material deposition.
What does the charge (Q) represent in Faraday's laws?
Recall what is flowing during the electrolysis process.
What does Faraday's Second Law state about mass deposition during electrolysis?
Think about what variables affect deposition during electrolysis.
True or False: Faraday’s Second Law can be used to predict the mass of different substances deposited for the same charge.
Consider how equivalent weights come into play.
A current of 1.5 A passes through an electrolyte for 15 minutes. Calculate the mass of copper deposited if the equivalent weight of copper is 31.75 g/equiv.
Use the charge calculation to apply it to the mass deposition.
In a laboratory, an experiment is conducted where various salts are electrolyzed for the same charge. If 0.5 g of lead is deposited, find out how much barium weighs if its equivalent weight is 137 g/equiv.
Set up the ratio based on their equivalent weights to find the mass of Barium.
