1) How does the electrode potential change with concentrationa)for deposition at a Pt electrode?b)for deposition at Hg? • a) For reduction, the required potential gets more -ve as the concentration decreases • b)For redn, the required potential gets more -ve as the % deposition increases • The actual concentration has no effect at Hg
2)At what potential will 0.035 M CuII start depositing?Electrode is PtEo = 0.339V
At what potential will 0.035 M PbII be 99.9% deposited?Assume electrode is PtEo=-0.126V
