What is Brian's Equation for cell potentials?
E cell = E cathode - E anode
Standard Hydrogen Electrode
Saturated Calomel Electrode
SCE electrodes aren't good above __ oC
Which responds faster, and SCE or Ag/AgCl electrode?
Electrode of the first kind
A single reaction, the electrode measures its own metal
Electrodes of the Second Kind
- Electrode forms a precipitate with an anion a and therefore responds to the anion's concentration.
- Example: Ag/AgCl electrode (Ag senses [Cl])
Can inert redox electrodes measure the absolute concentration of an analyte?
No, they just give you the ratio (good for titrations)
Atoms arranged in a repeating 3-D structure
- Oxidation Reduction Potential
- (a pH meter mode that gives you mV readings)
What part of the pH calibration equation changes with temperature?
The slope (it's only -0.0592 at 25 oC)
What kind of crystal is a fluoride ISE?
- A single crystal
- LaF3 doped with Eu2+
(give two examples)
- Total Ion Strength Adjustment Buffer
Give an example of a mixed crystal electrode
