Show hintHide hint
Remember the relationship of mass and charge.
Question 2.
Write down the formula that represents Faraday's First Law.
Show hintHide hint
Look for how mass relates to charge in electrolysis.
3Question 3.
What is the relationship between mass and electric charge in Faraday's First Law?
- Mass increases with charge
- Mass decreases with charge
- No relationship
Show hintHide hint
Think about how more electricity would affect a deposit.
4Question 4.
True or False: Faraday's First Law applies only to metals.
- True
- False
Show hintHide hint
Consider what happens in different electrolysis scenarios.
Question 5.
In an electrolytic cell, a current of 3 A is maintained for 1.5 hours. If the electrolysis leads to the plating of silver and the charge needed to plate 1 mole of silver is 96500 C, calculate the moles of silver deposited.
Show hintHide hint
Use the relationship from Faraday’s First Law.
Question 6.
If an unknown electrolyte deposits 5 grams of a substance after passing 1.2 x 10^5 C, can you determine the constant k if the substance has a molar mass of 40 g/mol?
