WitrynaTranscribed Image Text: Potassium hydrogen phthalate (KHP) concentrations can be determined through titrating samples of KHP (a monoprotic acid) with bases such as NaOH in the presence of an indicator such as phenolphthalein. The indicator is colorless in an acidic solution and turns pink in an alkaline solution. Thus, we can establish an … Witryna30 sty 2024 · To do that you use. Ka = [H3O +][A −] [HA] Another necessary value is the pKa value, and that is obtained through pKa = − logKa. The procedure is very similar for weak bases. The general equation of a weak base is. BOH ⇌ B + + OH −. Solving for the Kb value is the same as the Ka value. You use the formula.
