Question

(a) How many moles of mercury will be produced by electrolysing 1.0 M Hg(N0₃)₂ solution with a current of 2.00 A for 3 hours?
[Hg(N0₃)₂ = 200.6 g mol^-1]
(b) A voltaic cell is set up at 25 °C with the following half-cells:
Al³⁺(0.001 M) and Ni²⁺(0.50 M)
Write an equation for the reaction that occurs when the cell generates an electric current and determine the cell potential.
(Given;E_Ni2+/Ni= – 0.25 V,E_Al3+/Al= – 1.66 V)
