Quizplus · Accepted Answer

The concentration of hydroxide ions, OH-, in a solution can be determined by understanding the dissociation of NaF in water and the subsequent reaction of F- with water to produce OH-. Without the specific details of the reaction or the Kb (base dissociation constant) for F-, it's challenging to directly calculate the concentration. However, given the options, the correct answer must be derived from applying the principles of equilibrium and the dissociation of weak bases in water. The choice provided suggests a calculation based on such principles, indicating a moderate level of ionization and the production of OH- ions in the solution.
