3 cards from this section. Quick, good the night before a test.
Define Faraday's Second Law of Electrolysis.
Think about the relationship between mass and equivalent mass.
What does equivalent mass represent?
Relate it to the concept of chemical reactions.
What does Faraday's Second Law state?
Think about the relationship expressed in m1/m2 = E1/E2.
True or False: Faraday's Second Law can be applied to any electrochemical process.
Recall that these laws are foundational to electrochemistry.
A solution contains copper ions and zinc ions. If 100g of copper is deposited after passing 10C of charge through, and the equivalent masses are 63.5g/equiv for copper and 32.6g/equiv for zinc, how much zinc will be deposited?
You need to find mZn based on the set ratio using equivalent masses.
A technician is electroplating silver onto jewelry pieces. If the jewelry requires 25g of silver and silver has an equivalent mass of 107.87g, how much charge must be passed through?
Think in terms of how electrical charge relates to mass deposited.
