The titration curve for a weak base - strong acid titration is different than that of a weak acid - strong base titration. The curve begins at pH 11 and slopes downward gradually until the equivalence point is reached. At the equivalence point, the curve slopes downward sharply and evens out...
内容提示: Weak Acid—Strong Base Titration Curves (teacher notes) To draw a this titration curve accurately from scratch would take a long time, so this example is done for you. You MUST be able to draw a rough sketch of this curve. Again, this type of titration has the 4 stages: 1...
Titration Curve for Weak Acid MixtureDavid T. HarveyDePauw University
In this chemistry experiment, you'll be learning how to find the concentration of an acid using titration with a weak base. By the end of this...
IT has been supposed in the past that substances with feebly acidic or basic properties, say with Kor Kless than 2.5 脳 10in the case of N/20 dilution, are incapableof estimation by acid-base titrations. I have recently succeeded in elaborating a technique by which this object can be ...
A linear titration equation for determination of weak acids in the presence of small amounts of a strong acid is derived. The titration is performed potentiometrically. Equal volumes of the titrant are added stepwisely. More satisfactory results are obtained from the determination of an extremely ...

32 Experiment P (Titration of a Weak Acid): A sample of acetic acid (initial concentration 0.500 M) was titrated using NaOH and a titration curve was prepared. An experimental value for pKa of 4.65 was obtained. Which of the following specie...
1) mixed weak acid titration 混合弱酸滴定1. In mixed weak acid titration, calculation of PH of stoichiometric point, calculation of end point error and stepwise titration criterion are the must specific problems. 在混合弱酸滴定中,化学计量点时PH值计算、终点误差计算,分步滴定判据是三个必须明确的...
