Electrolysis and Faraday’s laws
Answers are for parents and teachers.
1
k = 0.329 mg/C, I = 3 A, t = 1000 s. The mass of copper in mg?
987
2
Silver (k = 1.118 mg/C): what charge in C is needed to release 1118 mg?
1000
3
If A = 27 and Z = 3, what is A/Z?
9
4
If the current doubles in electrolysis, how does the mass change?
It doubles, because m = kIt.
5
Write a safety rule related to electrolysis.
Solutions may be poisonous: only the teacher does the experiment and nothing is tasted.
