Ions that react with Ag + can be determined electrogravimetrically by deposition on a silver working anode:
Question:
Ions that react with Ag+ can be determined electrogravimetrically by deposition on a silver working anode:
(a) What will be the final mass of a silver anode used to electrolyze 75.00 mL of 0.023 80 M KSCN if the initial mass of the anode is 12.463 8 g?
(b) At what electrolysis voltage (versus S.C.E.) will AgBr(s) be deposited from 0.10 M Br-? (Consider negligible current flow, so that there is no ohmic potential, concentration polarization, or overpotential.)
(c) Is it theoretically possible to separate 99.99% of 0.10 M KI from 0.10 M KBr by controlled potential electrolysis?

Step by Step Answer:
a The electrogravimetric equation shows that for every electron transferred one Ag atom is deposited on the anode Therefore the number of moles of Ag ...View the full answer
