Question:

(a) Suppose that the reservoir in Figure 25-8 contains 1.5 L of 2.0 M K2PO4. For how many hours can the reservoir provide 20 mM KOH at a flow rate of 1.0 mL/min if 75% consumption of K+ in the reservoir is feasible?
(b) What starting and ending current would be required to produce a gradient from 5.0 mM KOH to 0.10 M KOH at 1.0 mL/min flow rate?
