Indicator Electrode--Quantification (Homework) Homework Unanswered If a platinum indicator electrode is used to measure [Cu2+] (standard reduction potential of Cu +is 0.337 V), and [Cu2+ o.0053 M, what is the cell potential (V) if the reference electrode...
Standard potentials are measured against the standard hydrogen electrode (SHE). Because it is not always convenient to use a S.Н.Е., often other reference electrodes are used. The saturated calomel electrode (SCE.) is one commonly used reference electrode, with a reduction potential of +0.242 V versus the S.H.E. Using a table of standard reductions, determine what the standard reduction potential of each reduction half-reaction would be versus the S.C.E Cl2 (g) + 2e-→ 2 Cl-(aq) E1.36 Fe3 + (aq) + 3...

Potential (mV) [Br](M) 0.300 Calibration data for a bromide ion-selective electrode (ISE) was collected and recorded in the table. The potential of the ISE was measured against a saturated calomel electrode (SCE). All solutions were buffered at a pH of 7.56. A linear calibration curve can be constructed from this data as a plot of potential (in mV) vs. pBr. Determine the slope and y-intercept of such a plot of the calibration data given. -21.2 0.0300 36.2 95.7 0.00300 0.000300...
