Reference no: EM13343207

Consider the controlled potential electrolysis of an Zn2+ solution using the following electrochemical cell set to -1.207 V: SSCE || Zn2+(aq)| Zn(s) 3.440 Coulombs of charge is collected in the electrolysis of a 50.00 ml solution. a) What is theZn2+concentration after the electrolysis? b) What was the original Zn2+ concentration BEFORE the electrolysis? The following electrochemical cells may be required in the calculations: E° vs. NHE SSCE E = +0.222 V Zn2+ + 2e- = Zn(s) -0.763 V
