Isoelectric
Having the same electronic configurations.
Oxidation Numbers
Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).
Hydration Energy
The energy change accompanying the hydration of a mole of gase and ions.
Voltage
Potential difference between two electrodes, a measure of the chemical potential for a redox reaction to occur.
Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
Ionization Constant
Equilibrium constant for the ionization of a weak electrolyte.
Hydrogen-Oxygen Fuel Cell
Fuel cell in which hydrogen is the fuel (reducing agent) and oxygen is the oxidizing agent.
Calorie
The amount of heat required to raise the temperature of one gram of water from 14.5°C to 15.5°C. 1 calorie = 4.184 joules.
