WebIndicators are weak organic acids or bases that dissociate slightly in aqueous solutions to form ions, it a solution can change colour at different pH value. Suppose a NaOH … WebTranscribed 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 …
13.5: Acid/Base Titration - Chemistry LibreTexts
WebNote that in this reaction there is a 1:1 mole ratio of acid to base. This equation is valid for all acids that contain only one acidic proton. All of the acids that you’ll be titrating in today’s experiment have just one acidic proton. This means we can write the reaction of KHP with NaOH as: KHP NaOH H O NaKP 2 WebIn acid-base titrations, phenolphthalein is often used as an indicator. Phenolphthalein is an organic molecule that is colorless in acidic solution and pink to red in the presence of base. If the indicator is placed in an acidic solution it will be colorless. coming of age festival
