Sagot :
The mass of nickel metal deposited on the cathode is 2.004 g.
What is electrolysis?
When an ionic compound is decomposed into its elements by passing a direct electric current using a compound in its liquid form. The process is known as electrolysis.
At the cathode, cations are reduced and at the anode, anions are oxidized.
The main components used in the process of electrolysis are
- electrolyte,
- electrodes,
- external power source
Current passed through the solution, I = 0.150 A
Time, t = 12.2 hrs = 12.2×60×60 = 43920 sec
Charge, q = It = 0.150 × 43920 = 6588 C
At cathode,
[tex]Ni^{2+}(aq) + 2e^- \rightarrow Ni(s)[/tex]
Nickel metal deposited by (2×96487 C) = 58.7g
Nickel metal deposited by 6588 C = [tex]\frac{58.7 \times 6588 }{2\times96487}[/tex] = 2.004 g
Hence, The mass of nickel metal deposited on the cathode is 2.004 g.
