M16Q5: Interpretation of Titration Curves – Chem 103/104

WebbIn simple acid-base titrations a pH indicator may be used, such as phenolphthalein, which becomes pink when a certain pH (about 8.2) is reached or exceeded. Another example is methyl orange, which is red in acids and yellow in alkali solutions. Not every titration requires an indicator. WebbTitration curves are the primary means used to graphically represent titration data. There are two types of titration curves, the sigmoidal curve and the linear segment curve. The sigmoidal curves uses the pH of the analyte and the volume of the standard titrate. Webb1. Initial pH This is determined by the most acidic of the K a values and the initial concentration of the acid. (Same as above) 2. Half-way points At each half-way point, the pH = pK a of the group you are titrating. (Same as above). At this point in the titration curve, we are in a buffering region, and the curve will be relatively flat. 3 ... greenbrier west football score

WebbIn strong acid - strong base titrations, the pH changes from 4 to 10 at the end-point so a suitable indicator must change colour within this range Methyl red and phenolphthalein are suitable indicators for these titrations Methyl orange is not ideal but it shows a significant enough colour change at the end point so is widely used WebbA strong acid-strong base titration is performed using a phenolphthalein indicator. Phenolphthalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions. Neutralization occurs at pH 7.0 as there are equal moles of acid and base.

WebbExperiment 17: Potentiometric Titration Objective: In this experiment, you will use a pH meter to follow the course of acid-base titrations. From the resulting titration curves, you will determine the concentrations of the acidic solutions as well as the acid-ionization constant of a weak acid.

The pH of the solution starts above 7 as it is initially basic. The pH decreases as acid is added from the burette. However, the rate of decrease shortly decreases (flattens) due to the formation of a buffer.
