Answer:B
In fluoride ion electrode, the potential corresponding to level of the fluoride ion is described by which of the following equations when E is the measured electrode potential, Eo is the reference potential and A is the level of fluoride ions in solution?
A. E=Eo+0.0591 log A B. E=Eo-0.0591 log A C. E=Eo+0.0896 log A D. E=Eo-0.0896 log A
Explanation: In fluoride ion electrode, the potential corresponding to level of the fluoride ion is described by the equation, E=Eo-0.0591 log A. A is the activity or effective concentration of fluoride ions.
