Cell Potential
Cell Potential in Potentiometry = Indicator EMF-Reference EMF+Junction EMF
Indicator EMF
Indicator EMF = Reference EMF-Junction EMF+Cell Potential in Potentiometry
Reference EMF
Reference EMF = Indicator EMF+Junction EMF-Cell Potential in Potentiometry
Number of Moles of Electron
Moles of Electron = Charge given Moles/(Moles of Analyte*[Faraday])
Moles of Analyte
Moles of Analyte = Charge given Moles/(Moles of Electron*[Faraday])
Charge given Moles
Charge given Moles = Moles of Electron*Moles of Analyte*[Faraday]
Potentiometric Concentration
Concentration at given time = Potentiometric Current/Potentiometric Constant
Potentiometric Constant
Potentiometric Constant = Potentiometric Current/Concentration at given time
Potentiometric Current
Potentiometric Current = Potentiometric Constant*Concentration at given time
Moles of Electron given Potentials
Moles of Electron = 57/(Anodic Potential-Cathodic Potential)
Cathodic Potential
Cathodic Potential = Anodic Potential-(57/Moles of Electron)
