30. 31. 32. 33. (d) Cl + e C1²- What volumes of H₂ (g) and O₂ (g) at STP are produced from the electrolysis of water by a current of 2.50 A in 15.0 minutes? An unknown metal M is reduced by electrolysis from a solution of M(NO3)3. It took 74.1 s for a current of 2.00 A to plate out 0.107 g of the metal. Identify the metal. An aqueous solution contains a mixture of cations at the following concentrations. [Cd**] = 1.0 M [Fe²+] = 0.10 M [Ni²+] = 1.0 x 10-6 M In which order will these metal cations be reduced if an applied voltage to the solution is gradually increased? Consider the electrolysis of a solution that is 1.0 x 10-³ M in Ag2SO4 and 1.0 x 10¹¹ M in ZnSO4 with pH = 2.000. (a) (b) Calculate the minimum voltage needed to plate silver metal at the cathode. Will it be possible to plate zinc metal at the cathode once the concentration of Agt has been reduced to a sufficiently low value?
