What will be the change in electrode potential when the pH of 1.0 × 10-4 M solution of F is raised from pH = 5.5 to pH = 11.5. The potential of an ion-selective electrode is 0.05916 E= constant + B log([A]sample + EKAI:l1) where: z = -1 for fluoride ion and assume B = 1. Express your answer in units of Volt. Do not write down the unit.
