An electrolytic cellcontains a pair of inert metal electrodes in a solution containing 1.00 M nickel(II) sulfate at pH = 0.00. Hint: Recall that pH = -log10[H+]. The pH is increased gradually until the electrolysis product changes. What is the new product and at what pH does this occur?
It’s review question, I need this as soon as possible. Thank you 3) For thè diferential equation: (a) The point zo =-1 is an ordinary point.

Given the following electrolytic cell: The current is discharged into the electrolytic cell containing the solution CuSO4(aq) 1.0M at 25 oC. During the operation of the cell, copper Cu(s) is deposited on one electrode and oxygen O2(g) gas is released, near the second electrode. O2(g) + 4H3O+(aq) + 4e- 6H2O(l) Eo= 1.23V Cu2+(aq) + 2e- Cu(s) Eo= 0.34V A. Write...
