How many grams of zinc, Zn(s) are electroplated out of a solution containing Zn2+ (ag) if the solution is electrolyzed for 22 minutes and 12 seconds at a current of 1.59 amps? Submit your answer with 3 significant figures and do not include units. Answer:
From the initial measurements you determine the electrode slope is -56.7 mV. You measure the initial potential of an unknown to be 84.5 mV. After the addition of 0.1027 M fluoride the potential drops to 39.9 mV. What is the molarity of fluoride in the original, undiluted, unknown? Answer is 3.97. How to derive?
