Iodometry is viable for any compound with a lower value for this quantity than iodide.
Iodometry is viable for any compound with a lower value for this quantity than iodide. Reactivity series for single-displacement reactions are ordered by this quantity. This quantity is measured using silver and silver chloride in a one-molar solution of potassium chloride. In SI units, this quantity is 3.06 for fluorine, 1.229 for oxygen, and zero for (*) hydrogen, the last of which is used as a standard for all others. If the change for this quantity is positive, then a redox reaction is spontaneous. At non-standard states, it decreases by RT over nF times the log of the reaction quotient, according to the Nernst equation. For 10 points, name this quantity symbolized by a script E, measured in volts against a reference electrode.
