How long must a Electricity The Strength 0.45 A Flow, with from One of them CuCl2 Lthe island 3.5 g Copper discharged will be?
Notes : Identical exercise also At the same time, Subjects salts.
Lösung: - CuCl2: Ions Cu2+ Responsibility. Cl–
Cu2+ + 2e– → Cu, z = 2 - m/M = I·t/(z·F)
t = m·z·F/(M·I) = 3.5·2·96485/(63.546·0.45)
t = 23618 s = about. 6.6 h
